2001 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl 4A)
First I owned the car for a month, had to replace the engine because oil wasn't going to one of the rods. Now, 2 years later, it's sitting waiting to be sold for the same problem. Had about 100,000 on both engines. Had it in the shop all the time, it was never the easy things that were wrong either. I would not buy this car again.
