2002 Audi A4 1.8T Avant quattro AWD 4dr Wagon (1.8L 4cyl Turbo 5M)
The A4 is a great car. Looks great, drives great has probably the best interior of any car that starts under 30K and with options like Quattro you can understand why Audi has been so successful with this car.
Probably the best feature of this car is the relative sparsity of them compared to the BMW 3 series. I see at least 10 black 3 series cars every day on my way to work. So if you're looking for something a little special, the A4 is a great choice.
Quattro, the awesome highly modifiable 1.8 Turbo leatherette seats (so much better than real leather i can hardly contain myself) and the interior design.
Ship the 1.8T with 200 HP, everyone who likes that kind of HP chips their cars anyways why not just save everyone the trouble.
