I've had a base model for over 2 years now. I'm very happy with the performance, handling, and gas mileage. The car is beautiful and I've got some great and interesting compliments on it. It is great fun and I love it, but there are some bad points. As several others have said, the interior design is lacking. No storage space, bad cup holders, the temperature control is one of the worst I've seen (should have been more like my 2000 Firebird). I don't know why people complain about reliability. I have over 60,000 miles already (fun to drive, daily driver)and have had little to no problems. Too bad Pontiac folded, GM needs to keep producing these some how.
FUN, great performance and handling, great gas mileage, fabulous exterior styling.
Ventilation system, cup holders and inside storage. Battery placement needs some work as well.
