I just purchased a 2008 STS-V and wanted to know when is a good time to buy the extended warranty (GMPP) before the 50,000 or 2013?

You need to purchase before your warranty expires, but JUST before. As soon as you purchase the GMPP, it cancels any remaining original warranty left on the car. I called and emailed more than a dozen dealers and found one in Montana that sold the warranty for the lowest price. Good luck.
