CLEAN CARFAX! Arguably, this G6 beats the Honda Accord, Nissan Altima and Mazda6 on value. And at our price it's an excellent alternative worth looking at. This 2005 G6 sedan has good road manners even when driven hard, benefits of its long wheelbase and European-designed architecture. The interior is plenty comfortable, even for the whole family. It's a roomy car that offers good road manners and excellent overall function, and it's a lot of car for the money. It does its job well, whether driving in city traffic or long hauls on the highway.
