Not a lot of things have gone wrong with it, but a few minor things have. First example is my rear spoiler is retaining water after a hard rain or a car-wash. Second, my heads up display tends to fade every now and then. Finally, I have had to replace my instrument panel due to the difference in the speed of the heads up display and speedometer.
I liked the Grand Prix back in the late 80's, then I really loved them when they changed it to this new body-style.
This car handles great, but can improve with a more sports car minded suspension. I understand that its goal was for touring, but this car has too much power to have that type of suspension.
I love the way the Grand Prix's interior is laid out. It can use a little help in making the interior a bit tougher. What I mean by that is it's fragile trim. It's easy to brake or scratch such as the door trim or hood release. Other than that minor fact, I love the comfort that the Grand Prix offers. Being that I am 6'5, I had to search for the car that I fit most comfortable in and the Grand Prix was a good discision.
The supercharger makes the Grand Prix a great muscle car replacement now that I hear the Camaro and Trans Ams are being discontinued. I also understand that Pontiac plans on making a 300 horsepower Grand Prix to bring the muscle car fanatics a car they can relate to. I am really looking forward to owning one of these beauties.
All in all, the Grand Prix has a little bit of everything under it's belt. The Grand Prix has luxury and performance that has pleased me. I would definitely recomend a Grand Prix to anyone.
My heads up display dims too when driving. Does anyone know a fix for it other than that great car.
I believe that the mirror for it needs to be cleaned or something... But I'm not sure, you can try looking in the GTP forum at gtpworld. com.
I had the same problem of my heads up display dimming to. Then one day it decided to quit on me completely. I thought I would need to replace it, but after checking the fuse for it in the passenger side glove box, I found the fuse prongs corroded. I used some sandpaper to get rid of the corrosion and now it works completely fine.
