just recently got a 2007 grand prix gxp.. cant say ive ever been happier with a car. been driving trucks since i was 12 and i needed a car for fuel mileage and im very pleased. already i have a cold air intake and custom exhaust. has had many compliments. and if anyone has other easy parts to install please send a message my way. as of now im looking for a radio install and a system. been also looking for a nos system for just a little more "umph" only wanting to use the 50HP jet/s.
