First of all, I had this car for a year now and I absolutely LOVE it! However, I will only describe here the things you should watch out for if you plan on buying one:
Gas consumption: 11.6L/100km overall -T/C button near cup holder: I keep getting coffee all over it
Stock tires (Eagle LS) will wear out like you won't believe. I think they are summer-only performance tires. Expect to change them sooner than you hope
Common problem with steering column getting dried up. It starts to click when you turn -Glove box is so small and inaccessible you can barely keep an envelope in there (it was way bigger in my old Sunfire)
Power, looks, dual exhaust, engine sound, everything that actually matters. It's a 4dr family sports car with wide tires and low center of gravity, a perfect combination for stability and accident avoidance. Gadgets upon gadgets that come standard, some that I'm still learning.
Relocate the Traction Control button away from the cup holders. If you spill coffee on it and it becomes gooey then you press the button. Voila! it gets stuck on T/C OFF!... Sssmokin'! Bad stock tires. The thread worn out terribly and the side wall cracked at around 42,000 km.
