In my opinion, (I have g6et) If you look at the whole package of both cars they cater to different tastes obviously, I dont think it comes down to just one car is better value than the other kind of thing...My missus loves the g6et but not the xr6 just because of the hoon factor and the fact that the xr6's are pretty common, they look nice enough though...One caters to the sport hoon factor and one to the class and style factor, and a little bit understated but not granpa, they are fairlanes huh...
