My major complaint with G6 is the computer control build into the CD player, which prevents me from installing an MP3 player in this car. I must say that must the worst idea ever, as there was plenty of room to build them separately, and the G6 loses major marks for that (the design of the CD/computer controls is VERY boring).
I’m also very unimpressed with the performance of the V6 engine. Fuel economy is about 12L/100km (and that’s not booting the car; if you have a heavy foot you will use more), and that’s 80% city driving. Too much for my taste with the unimpressive engine performance, but might be OK for others.
Seats are not very comfortable; ever since I switched from my other car, I have lower back pain. But that’s just might be the break in period... time will tell, but I'm not impressed so far.
Overall car is OK, but I can understand the price depreciation on American cars, there just seem to be too many small problems and unimpressive interior design.
