GT - Dual tipped exhaust, leather interior, sunroof, 6 disk CD player w/ XM, Onstar, different wheel combinations. Came with ABS and I believe TCS.

GTP - Majority the same as GT, but supercharged.

GTP Comp G - Same as GTP with tapshift transmission and few other loaded goodies. Along with HUD and so on.

GXP - V8 5.3L LS4 front wheel drive flop. Leather all the other loaded jazz.
