1998 Pontiac Grand Prix GTP Reviews

Really great car and super fast when you have the need for speed. I even beat benz's and bmw's on the straight-aways.
Great Car picked mine up with 30,000 miles on it. Have only had minor issues as wiring, Lights, Battery, Wheel Bearings. Would recommend this car to anyone that loves a fast smooth ride that 3.8 motor is great. If you have the GTP I would recommend PFYC.com they have great parts for upgrading your ride.
