I have the opportunity to buy a good low mileage 1998 Supercharged M3. What are your experiences with that car. Any problems?
The other option is to buy a 2000 Audi S4 and equip it with H&R Coilovers and the MTM Stage 3 upgrade. With a Stage 3 upgrade the S4 will be using all stock turbos running at only 1 bar of boost with a turbo back exhaust. This mod will make 350 horsepower. With all wheel drive I expect that 0-60 will be in the 4.8-4.9 range (based on the fact that people have been getting 5.0-5.2 times on chipped 305-320 HP S4's). I know this might not be quite as fast as a supercharged M3, but what about reliability. It is my feeling that the Audi might hold up better in the long run. Any opinions welcome. I am not sure which way to go. With all the S4 mods listed above + the car, price would be about 45-46K. Thanks,
