1999 Pontiac Grand Prix GTP - 85K Miles (Page 1/1) hye_4_life SEP 04, 12:02 AM I have a black 1999 Pontiac Grand Prix GTP with black, leather interior I'm looking to sell or trade. It has a 3.8L supercharged V6 mated to a four speed automatic transmission. I am the second owner, and the original owner and I have taken great care of the car. It has just over 85k miles and has many options including power windows, power door locks, power trunk release, power mirrors, power adjustable driver's seat with lumbar support, heated driver's seat, heads up display (HUD), automatic dual zone climate control, cruise control and radio control on the steering wheel, rear seat pass through to trunk, premium wheels, fog lights, automatic headlights, spoiler and remote entry. The previous owner had Magnaflow mufflers installed and recently I had Polk speakers installed in the front doors and rear shelf. I recently smogged and registered the car and it is good until July 2013. The car runs and drives great and is very clean inside and out but it's averaging 17.7 mpg on mostly city driving so I am looking for a smaller, more fuel efficient car. Asking $6500 OBO or trade for a first generation Honda Insight with a manual transmission or Honda CBR250.
