You get into engine trouble if you run lean! They can take lots of track time and come back for more. Eliminate any possible intake vacuum leaks, make sure the fuel pumps work (there are 2), replace old wires, plugs, cap, and rotor, install an oil-pan baffle, and keep the oil level up a hair above full. Check out Korman's website on E30 M3 racing/track tips:

Mine has 173k miles on it, running not as strong as a new engine, but still tears up the asphalt! Any M3 you look at, get a compression and leakdown test performed. This will determine if you need a rebuild soon or not.


It's all about "boy-racers". Like anything, if it's maintained properly, it'll run forever. The driveline is very strong, particularly the S14 motor. Often described as bulletproof, 150,000 miles isn't uncommon before the big rebuild, sometimes closer to 200,000 miles. Rebuilding can be expensive, but it costs a lot to re-do a 2002 (which, by the way, was the best BMW ever built!)

It's the buzzers and whistles that are more likely to give you a challenge, along with the usual wearout items (these cars are a minimum of 12 years old, most are 14), and of course, bodywork. They're great cars and will give many more years of competitive service. 15 or 20 years from now we'll see if they can match the 2002s record for longevity!

Happy motoring!
