1997 Pontiac Grand Prix SE 4dr Sedan
I wrote a review about 3 years ago when I first got the car. It now has 210,000 miles and seldom has to go in the shop. I usually get 24-26 MPG, but on long trips I've gotten 34 (really). It has never left me on the side of the road, but I did have to make some costly repairs when I first got it. I might buy an 07 or 08 soon, so I thought I'd update my comments!
Comfort, reliability, decent gas mileage, 3800 engine power, smooth ride.
