I drive a 2001 Pontiac Firebird Trans Am - black and mean lookin'. I don't drive it everyday, I just kicked 65,000 miles over on it. We commute in the Subie especially in winter (icy mountain roads + big V8 RWD car = potential for problems). We just paid it off recently so we'll keep it a while. I like to keep the same car for 6-8 years. We've had it right at 5 years. I have to replace tires every 20,000 to 25,000 due to my driving habits, and I've had the differential rebuilt (also due to my driving habits - but I upgraded the gearset for better low-end power). Other than the differential rebuild, I've not had any major problems with it.
The minor stuff: my driver's side window doesn't want to come back up once it's down (I talked to a GM tech and he said that is probably covered in a window motor recall notice - that problem started happening last summer). The seatbelt holder on the driver's side has split from the seat (thanks to my daughter hanging from it as she gets out of the car). The Pontiac Firebird / Chevrolet Camaro (known as F-body cars in GM language) ended production in 2003 so you can't buy 'em new anymore. There's a new Camaro concept car at the Detroit Auto Show right now, but it won't enter production until 2007 or 2008.
My wife drives a 2003 Subaru Legacy wagon. Metallic green with about 75,000 miles. We've had it 2 1/2 years. She likes to keep her same car 2-3 years. I'm not sure how much longer she wants to keep driving it, but it's a good car. She may go up to something else (her car buying history & my common sense tells me), in which case the Subie will become my daily driver - and then when Da Son becomes of driving age that can be his car. I call it our little billy goat - not much to look at but it is a very good car. The only things I can think of are:
the rear cupholder broke (might have had something to do with my daughter standing on it), and the throttle plate stuck a little (they cleaned it which was NOT covered under warranty as a 'wear item').

I'm saving up my pennies, nickels & dimes for a Corvette Z06. Awww yeah, baby.
