2005 Mercedes-Benz C-Class C230 Kompressor Rwd 4dr Sport Sedan (1.8L 4cyl S/C 6M)
This car is an absolute blast. It blows the C240 away. If you are looking for something that is reasonably quick yet cheap, this is your car. However, maintenance is quite expensive. Just went through the first oil change, $65! The thing requires Mobil 1 SuperSyn 0W- 40 and there are only a couple of places you can buy that. Approximate cost is $7.50 a quart. Other than that, enjoy.
Love the package options. Got the one with all three, headlamp, sunroof, and sound system options. Also got the automatic. Makes life so easy. The sound system is awesome for a "stock upgrade" system.
The only thing I wish they would do is offer the Kompressor for the 320. I would have bought that car, but it only had 25 more horsepower out of a V6, and it was really not all that much faster. The pickup from the supercharger is amazing.
