2002 Audi S4 quattro AWD 4dr Sedan (2.7L 6cyl Turbo 6M)
This is an all around great car. It's an absolute blast to drive, and you can blow away most cars you'll encouter at the red light on your way home from the grocery store. Plus, it's just a little bit different, which is always good.
Definitely the engine. It really is a car that you get in, sit down, shut up, and hold on. Once you step on the gas, you're in for a real ride!
German cars and their lack of features: why couldn't they put a CD CHANGER in the dash? Our 2001 Honda Accord with a sticker of $21k had that in it. ALso, this car would be even nicer if the back seat were just a little bigger.
