The Gxp G8 is smoking hot. If you've got the extra cash available and want a 5 year 100K drivetrain warranty....then the gxp is a hell of a deal. (especially if you have to have a six speed manual tranny)
The GT is a great deal for the money and probably the one I'd go for since I want an automatic trans...
I'd buy one off the dealership selling them on this site with a few miles on them. I've seen a few hundred mile examples going for 23 or 24 grand..
Thats a number thats hard to beat..
The dealership is ohio I believe and he posts on this site a few times...with cars that are available for sale..
