Welcome to the forum.Hello, am I nuts for looking into a 2008 SLT with 35K on it? One owner and looks sharp but I mean it's a 2008!! Judging by the miles most of you have on yours I'm guessing the opinion will be do it!
Be sure to check the vehicle's service history with GM. Ask a dealer to run a GMVIS report - you'll just need the VIN. That will tell you how well the previous owner cared for it.
