I traded in the SUV and bought this car for a high mileage commute. I could not fit comfortably in the sub compact models available at the time and ended up purchasing a used G6. I have put 70,000 miles on my G6 since July of 07. I bought the vehicle with the driver package (XM, 6 way seat, fog lights, power pedals). I drive mainly open interstate and get about 29 MPG average which I think is pretty good based on the size and power of the vehicle. I have had the car in the shop for warranty fixes on the XM radio and the electric power steering (69 k almost missed factory warranty extension for this known problem). I currently have 96k miles on the vehicle and have had no other problems.
XM radio, rear seat space, rear fold down seats
Better driver seat and fix the electronic gremlins
