2008 Pontiac Grand Prix GXP 4dr Sedan (5.3L 8cyl 4A)
I have had my GXP for few months now. I had an 04 GTP and I must say that having the GXP is a big difference. The rumble from the exhaust is much greater and once you step on the gas you go. The tires are summer tires though which is a concern living in Chicago. Overall it's a blast to drive.
Powerful V8 engine, front bumper design over the standard Grand Prix, sued inserts, leather and I like how the GXP package comes standard with almost every option. The G8 GT doesn't come with leather and such standard. I also like the enhanced wide track for cornering.
Too much torque steer. It makes you hesitate to give the gas and keep control. Come out with a nice hood that has ram air scoops like the GTO, G6 and G8 GT.
