For sale is an exceptional Grand Prix GTX made by SLP modifications Inc. A GTX is born when the Grand Prix buyer requests their new GTP to be sent to SLP modifications before they take it home. This is done while the car is still new, so that it can be represented as a factory option. Specific to 2003 GTXs, SLP installs their own functional Ram Air hood, GTX labeled headrests, GTX trunk lid with high tail spoiler, GTX graphics for hood and trunk lid, SLP exhaust system (sounds excellent!), and upgraded suspension. There is more that I may be forgetting, total horsepower I know is near 260hp. Factory installed options include, heads up display, heated drivers seat, power moonroof, chrome wheels, BOSE stereo, information display with digital boost gauge, and much more. The cars history is phenomenal. Has had one owner since new and has been accident free. Tires, brakes, and suspension all look very good. ---HAS ONLY 111,245 ORIGINAL MILES---3800 V6 doesnt leak or burn oil, supercharger sounds very healthy. Car has been fully detailed. Non smoker interior is very nice and all power options work well. Exterior shines like new, completely rust free. GTPs are getting harder to find unmolested and adult owned, let alone impossible to find a one owner, adult owned GTX. Must see. Only $5,950. , 616.299.3210
