Intake manifold gasket replaced today at 76,000 miles, no recall on this, and thousands of people have had this problem. Also with 76,000 miles on it, today the mechanic calls me when he's done with the $600.00 intake manifold gasket and tells me the catalytic converter is stopped up, informs me that its covered under GM 8yr 80k mile warranty. Also replaced the fuel pressure regulator today at the tune of $90.00, and wasn't charged any labor.
I love the car, wish it would hold together for me, it rides great, has good power, and plenty of room.
I'd stick with this car. In looking over the number of satisfied owners in the various categories there seem to be more "smiley faces" on the Grand Prix site than on most others. A lot of folks get well over 200,000 miles out of these cars. The 3.1 does have a gasket problem, but other than that they are usually very trouble-free cars.
