1998 Pontiac Grand Prix GT 4dr Sedan


When I purchased this car in '03 with 40,000 miles on it, it was about 5 years old. Being a GM car, I expected it to run into some nickel-and-dime type problems, but got more than I bargained for. I was told that the 3800II engine was ultra-reliable, but came to learn that from 97-99 roughly, the plastic intake manifold was suspect to cracking and coolant leaks, leading to VERY expensive repairs. Read below for specific problems/etc.

Best Features

- Good low-end torque, though not as quick as it should be given the power. - When properly running, great gas mileage for a car with this kind of power. - Fairly comfortable seats and room to haul your friends around

Worst Features

Major problems: *** plastic upper intake manifold leaks Roughly an $800 repair - headlight lenses will fall off(97-98) $50 - idle pulley seized up - about $300 repair - window got stuck - $50 part+labor Minor Complaints: - lots of road noise - hood of car easily chipped - lots of sqeaks/rattles
