I just bought an 07 GXP with 59K on it and it runs great. I have put over 3K on it this month and it doesn't burn any oil and I have had zero problems with it. The car is a blast to drive and I absolutely love it. I have owned grand prix's since 1988 and this is by far the nicest riding one I have ever owned. It also get's pretty good gas mileage for a 3600lb car with a V8 in it. In my humble opinion, Pontiac did a pretty good job with this last generation W-Body.
