I have only had a few problems with it, but you have to remember that this is my first car, so I wouldn't have anything to compare to (actually a '98 Camry, but that isn't much to compare to).
One of the annoying things is that if you press the pedal down hard, and fast, it takes a second or two for the power to kick in and then you start going fast, I'm not exactly sure why, but it isn't a fun surprise. The gas seems to go quick too, it's supposed to be 22/30 (don't quote me on that). Another problem would be the cup holder placement. It's hard to move the shift knob when you have a drink because the cup holders are placed in the center inbetween the two front seats. The center console with the a/c knobs and CD player does look a bit cheap. There is tons of front leg room also. There is plenty of headroom in the front, but sitting in the back is a pain for any one over about 5ft 7in. Other than that, it's great. The engine sound great, especially from 3000 to 5000 rpms. It handles nicely too. I rarely have to turn the wheel over 90 degrees either way. The seats are wonderful (I have the black leather). They keep you in nicely and they are soft too. My friend who owns a 5 speed GT says that the shift gates are narrow and it's easy to mess up and shift to second instead of 4th. If you have any other questions, just feel free to ask.
