The Short Story

The 2000-2005 BMW M3 (E46) is a bona-fide legend in car culture. The 8,000-rpm, 333-hp, individual-throttle-bodied S54b32 straight-six comes at the end of a 25-year sentence for BMW; it never produced a naturally aspirated straight-six M car again. The E46 debuted in the heyday of hydraulic steering, rear-wheel drive, unobtrusive traction control, stability control, and slightly simpler motoring.

It also marked a shift from the previous E36-generation M3. This car was the first of the comfortable, quiet, and refined grand-tourer M3s. Its primary competition being the B6 Audi S4, and the Mercedes-Benz C32 AMG, it was still uniquely connected to motorsports and certainly the highest performer of the three. Paired with the new-to-the-M3 SMG II automated manual gearbox, or the classic six-speed manual, the M3 was sure to gut punch you in the midrange and parkour its way to redline.

Fast Facts

The S54b32 has its roots in the European market S50b32 of the Euro-spec E36 M3. Yes, the b is lowercase.

The E46 M3 features a mostly unique arrangement of suspension arms, specifically made for the M3 out of cast aluminum.

The M3 also featured a unique rear subframe to mount the M differential.

The SMG-II gearbox was an automated version of the standard manual with a single dry clutch, not an automatic. This means that a computer and Mechatronics shifted the car for you, slowly and aggressively.

The S54 engine had some of the highest horsepower per liter in its era, just behind the Honda S2000. That figure for the M3 was 104 horsepower per liter, at 3.2 liters.

Spotter’s Guide 

An M3 is easily distinguished from a normal E46 3-series. For starters, the E46 M3 is a two-door coupe. The most obvious visual differences are the widened fenders front and back and front fenders that feature a small grill that bears an M3 badge. Up front, the car has a unique front bumper, and the hood now plays host to a “power bulge” to signify the extra power of the M3.

Around the back, an M3-specific rear bumper compliments the decklid spoiler. Quad exhausts belch the chainsaw shriek of the S54. Throughout its life cycle, the M3 never received a full LCI — BMWspeak for face-lift. The main exterior differences are LED taillights added for the 2003 model year. The headlights remained the same for the duration of production. A finned differential cover under the rear of the car is easily spotted if you’re driving behind one and can’t see anything else.


Exactly 26,202 M3 coupes made their way to North America, along with 17,577 convertibles — plenty to go around.

Important Trim Levels and Options

The E46 M3 didn’t have many options besides interior and exterior color. This car was, after all, the top of the range for the ubiquitous BMW 3-series in the 2000s. There was an option for a factory navigation unit with minimal integration as well as a sunroof-delete option.

Most M3s were produced in Silbergrau Metallic (silver grey), so that’s the easiest color to find and generally the cheapest. The blue models, such as those in Laguna Seca Blue, Mystic Blue, and Interlagos Blue, are the most desirable and expensive M3s. Phoenix Yellow is a polarizing color. As such, it either commands a premium or condemns the car to sit around for a while, depending on timing.

Imola Red is also a common but desirable color. All the colors mentioned are M-only colors; the rest of the more common colors, such as Alpine White, do not command a premium.

Sunroof-delete cars are rare and desirable as well. Interior colors in the U.S.-spec models were limited. Black Nappa and gray Nappa leather are the most common interior hues. The most desirable interiors from a collector’s perspective are Cinnamon leather and Imola Red leather, the latter of which is the rarest of the lot.

My personal experience with BMW manual gearboxes: long throws like chopsticks in butter and long clutch-pedal travel. A good short-shift kit fixes everything. The long clutch isn’t a problem, and you come to appreciate the smoothness it affords.

The big bummer with these cars is the universally hated SMG II gearbox. It uses the same Getrag gearbox as the manual but it’s automatic. We hear a lot of SMG pump this, burnt clutch that, and generally it’s true. The best way to fix the SMG problem, is to re-manualize the gearbox with this useful guide. The six-speed manual cars are the most desirable bar none, with SMG knocking thousands of dollars off asking prices across the internet.

The M3 came in two body styles, coupe and convertible. The convertibles are substantially less valuable and the cheapest way to get into an M3. Functionally, they’re similar, but the convertible features extra reinforcements to make up for lost rigidity.

Europe received the SMG-gearboxed M3 CSL, which stands for Club Sport Lightweight. It featured a new airbox, suspension tuning, wheels, and the removal of a lot of sound-deadening materials to achieve the rawest M3 experience possible in the era.

All things being equal, the most affordable M3s will probably be be Silbergrau with gray Nappa leather, and the most expensive will be Laguna Seca Blue with Cinnamon interior.

General Reliability and Ownership Cost

These cars can be perfectly reliable — after some intense maintenance and modification. People regularly track their E46 M3s hard and enjoy many thousands of miles in their cars. It’s not unheard of to see one rack up more than 200,000 miles. Don’t expect this to be a cheap car to run, however. Parts cost is generally in the hundreds to thousands of dollars. A lot is unique to the M3.

At the time of this writing, you can expect to acquire a decent E46 M3 for anywhere from $15,000 to $40,000, depending on factors we’ll get into below. If you drive it regularly, expect to spend a few thousand dollars a year keeping it running in tip-top shape.

The good news is that there are a host of aftermarket companies that make parts that permanently address the common issues with this era of M3.

Obscure Details

The E46 platform is ultimately a massive evolution of the original E30 concept. The front suspension is highly similar, especially in the non-M cars, where the M3 has had some major work done to change geometries. The rear suspension is more closely related to E36 but still massively changed for the M3.

The S54b32 is an evolution of the euro-only S50b32. The S50’s heads are rumored (but not quite confirmed) to have been the basis for the cylinder heads of the McLaren F1. Thereby, your S54 might be half of a McLaren F1 S70/2 V-12.

Red Flags and Known Issues

The E46 M3’s common issues are well-known and documented. Luckily, they’re pretty easily identified as well.

Look out for:

Rear subframe issues. Strictly speaking, the subframe isn’t what tears, it’s the actual unibody structure of the car itself. This can usually be felt by some looseness and the alignment (straightness of the wheel) changing over some wavy or cambered road surfaces.

Connecting-rod-bearing problems. Early E46 M3s (2000-2002) are infamous for issues with the connecting-rod bearings. This mostly stems from the heavyweight motorsports oil that BMW specifies for this engine in cold starts. The best way to find out if you have this issue is to collect a sample of oil from the car you own or want to buy and send it to a company such as Blackstone labs to analyze the oil before it’s too late. The oil analysis will tell you if it’s happening earlier than you think.

VANOS problems. Beware of these. VANOS is a variable valve-timing system meant to improve drivability and economy. It stands for Variable Nockenwellen Steuerung. Early M3s had faulty bolts that held the camshaft sprocket to the camshaft itself. The bolts got loose and fell off, causing catastrophic damage. There is also the issue of the mechanical VANOS itself failing. This issue will present itself as an engine rattle at around 4,000 rpm. The longer you let this go, the more likely it is that the internals of the VANOS unit on the camshaft will break the tabs that hold it together, fall into the VANOS pump that pumps oil to the VANOS, and cause it to completely fail. Oh, and the electrical solenoids can fail and cause reduced power. Luckily, the engine won’t blow for that one.

Electrical Issues. Look out for electrical problems. These cars have a full array of sensors to keep the engine happy, and they fail with some regularity. BMWs also tend to eat coil packs every 60,000 miles.

Oil Leaks. BMW oil seals are generally garbage. Look out for leaks with the oil-pan gasket, valve =over gasket, and the oil-filter-housing gasket.


The E46 M3 has seven recalls documented on the NHTSA website. Most relate to the Takata airbags the car is equipped with, and one relating to an inconsistency with the amber side markers. We encourage you to get the airbag recall fix immediately.

Where to Buy Parts

We recommend FCP Euro for E46 parts shopping. They have specialists on the other end of the phone, access to every BMW-specific part, and the added bonus of easy DIY kits for most minor and major M3 service.

ECS Tuning is very useful as a parts catalog to pull part numbers and cross reference, but we don’t recommend them because of shipping and quality woes.

Don’t be afraid to call your local BMW dealer parts counter for some help with part numbers, too. But, of course, OEM parts from the desk are rarely inexpensive.

Aftermarket Support

The E46 M3 has a colossal aftermarket. Twenty years of road racers, auto-crossers, factory racing support, and legendary status in the car community has driven development of every part imaginable.

There are off-the-shelf drift angle and road-race suspension kits for this car, every coilover manufacturer has a model for the E46 M3, and many engine mods can breathe a little bit more into the naturally aspirated S54.

Even better, the M3 aftermarket bubble drove the development of parts to fix every one of the M3s shortcomings. Upgraded VANOS kits, easy DIY subframe reinforcement kits, and upgraded rod bearings to increase the service life of the engine — everything is possible with the M3 platform. 

You’ll find a ton of M3s with CSL airbox mods for extra power and sound. A really good mod is a subframe reinforcement kit. It strengthens the trunk floor to prevent the infamous tearing issue. It is basically a must-do mod, along with an updated VANOS unit from a specialist such as Dr. Vanos.

As with any E46, deleting the clutch delay valve is a no-cost mod that fixes the weird clutch feel that can happen with these cars. There’s no downside, and it only helps increase clutch feel. The stock delay valve is dumb and feels dumb.

Doing the update 2003-plus rod bearings is a good mod, too.

Factory Service Manuals

The Bentley Service Manual is considered the gold standard in E46 reference texts. As of Feb. 8, 2021, you could access it here.

If that link’s dead, try Google or buy a hardcopy. We mentioned FCP Euro earlier. That site sells it for about $112. The book’s model number is B305 if you want to look around used-book sites, too.

An unofficial reference text that gets linked to a lot on BMW forums is the Mike Miller Maintenance Schedule. It has a comprehensive rundown of, you guessed it, what to change out and when.

Parts To Keep in Stock

Being an esoteric European sports car, the E46 M3 is prone to random failures that can leave you stranded at worst or stressed at best. It’s a car that definitely needs a small stock of spares or maybe even some additions to your road kit. Here’s what you might want to think about keeping around if you own one of these:

  • VANOS solenoid pack. It might be expensive but it is an inevitable failure at higher mileage.
  • 10W-60 engine oil. These engines burn oil naturally, it’s always a good idea to carry some around on a long road trip.
  • Coil packs. This is one that can happen anytime and leave the car running poorly or stranded. Keep a few in the trunk to easily fix a potential road trip ending problem.


The E46 M3 has the distinct motorsport accolade of being something of a rule-bender. The main racing version, called the BMW M3 GTR, took to the track in 2001 with a 4.0-liter flat-plane V8 engine that was specifically made for competition called the P60b40. It was a controversial decision for one reason: The engine had no connection to the S54 inline-six of the road car. The 2000 BMW M3 race car’s 3.2-liter inline-six was deemed not enough to beat the 3.6-liter Porsche 911s.

It competed in the American Le Mans Series (ALMS), which stipulated that racing parts must be homologated and sold to the general public. The outcry was that the V8 engine was not readily available to consumers and rival teams had a point — BMW claims to have made ten road-going M3 GTRs with the P60b40. There are only two that are known to exist. Meanwhile, the V8 M3 GTR won six of eight ALMS races in 2001.

For 2002, ALMS altered the rules and regulated the M3 GTR out of competition. Now, there had to be 100 road cars and 1,000 engines built for cars to meet regulations. BMW duly backed out of competition, until they brought the V8-powered winning machines back for the 2003 endurance racing season. The company won the 2003, 2004, and 2005 Nürburgring 24 Hours with that car. 

It was a true racing special and one of the coolest race cars ever made. All born from the desperation to win.

Professional Reviews

“2001 BMW M3: The more-powerful Euro version finally arrives here. Bring more cash, too.” (Car and Driver: Dec. 1, 2000)

Larry Webster at C/D seemed to have loved the M3’s savage drivetrain but didn’t enjoy the mild understeer and stiff ride. “The engine is an absolute gem. This ferocious, screaming motor hurtles the M3 down the road with an urgency that now rivals the world’s best sports cars from Porsche and Chevrolet.” “… But it has picked up a couple of bad habits. The first is a ride that’s more punishing than the last model’s.” “Yep, it understeers — badly.”

“Road Test: 2001 BMW M3. The world’s best sport sedan… again.” (MotorTrend – December 8, 2003)

John Kiewicz of MT thought otherwise on the M3’s handling, praising it with the electronic assists off. 

“Clearly, the DSC was designed to keep average schmoes from powering themselves right off a twisty mountain road, but we feel it chokes the M3 way too much for aggressive driving.” “Click off the DSC, and any hint of understeer can be counteracted with your right foot, allowing the capable pilot to balance the car as he wishes.”

Owner Insights

Here we’ll share observations and opinions from people who have actually owned these cars. You get a special treat in this particular Autance; Zack Klapman (of The Smoking Tire, Hagerty, and other cool car programs) was kind enough to give us a comprehensive rundown of his E46 M3 experience to date.

Zack Klapman (Feb 17, 2021)
2002 BMW M3 manual; stock; owned four years plus:

“If you’re thinking about buying an E46 the first thing to know is that you are correct and the whole world is about to be your subordinate. They are great. I love this car. It does so many things well. You will understand why the M3 has the reputation of a do-it-all and why it is such a special badge.

It’s fast enough to feel relevant. It looks modern without being over-styled. The stance (stock on 18s) is great. I think the ergonomics are excellent for long drives (as long as you have the center armrest, which you want) and it will give you 29 mpg on the highway at a decent pace. Few sports cars are so frugal with gas and yet can deliver fun when you stamp your right foot.

Fold the seats and you can transport a five-foot table top. Give it a detail and it can still turn heads. Maintain it and you can drive them hard for 200k miles, on road or track.

It’s small enough to parallel park yet doesn’t feel cramped. Should you feel inclined to go drifting you will find it has a surprising amount of steering angle.

It’s a great car as long as you’re prepared to maintain it.

Because you will maintain it. Oh yes, you will. If you’re buying a car today, almost regardless of mileage, you need to make sure the cooling system has been replaced and subframe has been reinforced. Ignoring those things is like giving a child a “childproof” lighter. Inevitably, something will go wrong.

There may be door rattles, or glues that wear out. Remember, this was a $50,000 car when it was new. Expensive cars tend to be complicated cars and complicated things break. Even when they were brand new they weren’t without issue. Go search the forums in 2004 and you’ll find plenty of questions and complaints. And now you, the brilliant but optimistic enthusiast that you are, are trying to buy a $72,000 car (accounting for inflation) for a third of the price. This is a bold bargain.

Some stuff I only learned after owning it:

The common problems aren’t the only problems. When you research these cars, everyone will tell you to make sure that the VANOS, subframe, and cooling system have been addressed. Those are the big problems so of course they rise to the top of the Google search results. They don’t tell you that it sometimes idles weird, or that suspension clunks develop every year as regularly as flowers bloom. Who knew you could pay for a PPI at a dealership only to buy the car, and on the drive home, find that the cruise control doesn’t work? Why are the windows jiggling after a few months? Because pillarless doors. You’ll be taking off the door card twice a year so you can tighten the bolts that hold said windows, fearful that you will crack the very windows you are trying to protect. Oh, and the coating they put on various interior bits will start to flake off so it will look like you Plasti Dipped your center console.

One lesson I learned that’s true of all cars: A previous owner (or mechanic) can make the car much worse than stock. What began as a strange rolling idle became a car running on 3 cylinders. A code reader told me that my O2 sensors were bad. After dismantling that whole system I found out that the REASON those sensors were bad is that someone had put them in the wrong place. The sensor for cylinder 1-3 was in the port meant for cylinders 4-6, and vice versa. You can imagine the hellish spiral of bad information this would present to the ECU.

As for what I wish I’d known before I got it:

I felt like I went into my purchase pretty informed. I spent months looking for a car and overall I’m happy with the one I got. I wish I had done 2 things differently:

1. Tested the cruise control. I could have negotiated on that because it’s an expensive pain to fix.

2. I wish I had brought a code reader that day. Maybe I would have caught the O2 issues and saved myself that three-week headache. I have no idea how long the car was running like that. Hopefully no long-term damage was done.

I plan to keep it for a few more years at least. I haven’t found a newer car that does so many things as well, especially for the price. The M2 would be the modern answer (and I love them) but they’re very expensive and their systems are even more complicated.”

What They’re Worth Now

The prime example: You’re looking at about $35,000-$40,000. This is for a primo color combo, low miles, one-owner, full service history, and no issues whatsoever.

A very clean driver: Budget about $25,000-$30,000. These cars have decent miles, but are serviced well, cosmetically 9/10, and well cared for with some road grime. This is what I call the “goldilocks zone” where the car has been driven and sorted, but well loved. This is also well within the budget for a great color combo

An honest car: Budget $18,000-$23,000. These cars will have driver miles, 100,000+. Service history will be mostly there, and ideally it’ll be a two-owner car. It will still be well loved and driven, and you’ll have some nice colors available, but mostly grey M3s will be in the rotation.

The budget option: $13,000-$17,000 will get you a reasonable E46 M3. There will be multiple owners, and many miles (over 130,000) but you can find a great option in this price range. Color combos are extremely limited, generally you’re gonna be looking at greys and the odd Pheonix yellow that’s been rotting on a lot. Some repairs will be required.

A roach: Anywhere from $7,000-$10,000 will get you a pretty rough M3, that will require most of the major repairs. These cars are high-performance and often crashed, so beware an accident history and bodywork. Miles will be in excess of 150,000, and honestly, you’ll mostly be looking at a lot of convertibles. 

Where to Find One for Sale

These cars are old enough that Craigslist is a great option for the more mid-range quality of an M3. Plenty of options will be on CL. 

If you’re looking for pristine examples, Bring-A-Trailer and Cars & Bids will be your best options; they cater to an enthusiast demographic. But since their reach is big, you can expect a good crop of competition on the buy. E46 M3s are popular enthusiast cars, so once one pops up on a big auction site it’s unlikely to fly under the radar and sell real cheap.

Generally, you won’t find any reasonably priced ones on the larger search engines such as KBB, AutoTrader, or AutoTempest. Dealer lots seem to ask exorbitant amounts for these cars, and they do not have the best examples. Steer clear.

What to Ask a Seller

Go-to questions should include:

“When was the last rod bearing service? Do you know if it was ever done?”

“Are there any strange suspension noises?” this is to eek out a subframe problem, without directly alerting an owner to what you’re asking, and trying to hide it.

“Does the car have a check engine light?” You should generally ask this, but most check engine lights on an M3 are bad news.

“How much oil does the car consume?” It’s rare that you’ll get an honest answer here, but sometimes you will. M3s are known to consume some oil naturally.

“Has the VANOS been repaired?” Best to ask this one directly, usually an enthusiast will know, and a flipper won’t.

Competitors to Consider

Direct competitors include the B6 and B7 Audi S4, and Mercedes’ C43 AMG. But for the price range, you could also consider a 2008-2012 BMW 135i, or even a 2007-2013 BMW M3, which are coming down in price. Newer Audis are coming down too, and a B8 S4 is well within range, as well as early 2008-2010 Mercedes C63 AMGs.
