Hello, I just posted on the Intro lounge.

My girl and I just purchased an 01' Grand Prix GTP Special Edition Sedan. The car has 140k miles on it, mostly highway, and I was wondering what should I check / do to this vehicle to ensure it has a long life. I am not looking to make this into a high performance power house, it's already quick enough. I just want this car to run and last us a long while. I have all the receipts on this car since 2003 from oil changes, tire rotations, to a complete overhaul in 2009 (I can find the receipts for further details).

I'm planning on changing the oil, trans fluid, super charger oil. What else should I look for?

Also the only issue with the car is that during acceleration or hard turning a vibration occurs. I trolled these boards and the GTP boards before and to the information i found it is probably due to a warn out CV Half Shaft. Apparently the problem has been going on in late 2008 but none of the mechanics could fix the issue. They thought it could have been due to bad alignment or incorrect tires, however, she has had all that done to it numerous times. So what CV Shaft should I buy? I kind of don't want Chinese bull you find at your common auto parts zone, I want something that will LAST!

Thanks in advance.
