The heads up display is awesome and the vehicle diagnostic center is very helpful tracking your mileage, mpgs, oil change intervals and fuel used/remaining!
The Bose stereo system rocks but no inputs :-( Working on getting an aftermarket stereo or expensive changer input toplug in an mp3 input or iPod.
The interior is perfect! I'm a big guy and I have more than enough space! All the gages and switches are easily accessible and visible... lots of cargo space, and passengers are comfortable.
Really thinking about going to a 2009 G6 ... when I retire this car! I've rolled with Chevy and Volkswagen the last 10 years and now I'm getting into Pontiac... very solid vehicles and the V6 is solid!
None that I can see! Brakes solid, handles very well and the 200hp is nice in the city and passing on the highway!
