there are alot of posts here with problems with this car
Remember that these posts are only the problems
that people are trying to solve. Even then, when you look at the entire population of GXPs the problems here aren't many. When I first joined I thought the same thing, but guess what? I've only had two of the three big known problems with mine - Intermediate shaft and fog lights. Try getting a car with a V8 and as loaded as a GXP is for about 18k. Na gonnna happn. You're only hearing the problems on BC club because this is where everyone comes to find out solutions. People don't post everyday saying "I had no trouble today but man did it handle well around that curve", etc. You are reading exclusively the negative and not the positive. Go to the "your ride" section and look at the praise heaped on the GXP. This is the "mechanical problems" page, therefore, you see all the problems.
My personal car buying philosophy is this - If I can't afford what I really want - an Acura RL, Lexus, etc. - I go for the best Pontiac I can afford. Yeah, I know I'm going to face more repairs than average down the road, but they are cheap, cheap, cheap repairs versus those other cars. Plus, I simply can not stand to buy a cloned "everybody" car, e.g. Camry, Accord, Malibu. Pontiac still has distinctive styling, especially the GXP. I've been losing respect for GM engineering (not styling) for years, but the price of a one year old program car has always drawn me back. I wouldn't buy any GM with +60k miles, especially after my experience with my old Grand Prix, but that is just my opinion.
My GXP has been remarkable and my SSE has been very reliable (at least until it got to 120k miles; it had some issues, but now it is great).
Bottom Line: The performance on the GXP is awesome and the handling is unbelievable. And I thought my SSE was The Best Car Ever.
