2006 Chevrolet Cobalt SS Supercharged 2dr Coupe (2.0L 4cyl S/C 5M)
First new car, used to drive a 1986 Chevy Monte Carlo SS. Much nicer car, better handling, no problems, great fuel economy, and much more comfortable. Only thing I've had to do so far is change the oil. I'm at 23,000 miles so far and it's been great. Interior is a little cheap looking, due to the plastic used everywhere, but the seats are fantastic (G85 Recarro package) but for a $20k car it's great.
Favorite feature is the supercharger. Instant power on tap. Second though would be the seats.
