I am going to be looking at a 2015 Suburban LTZ next week and was wondering what should I be looking out for? I've had a 2002 for the last ten years and it has been a tank, but is showing it's age. So far from what the seller has told me it sounds like a good vehicle and the pictures look good, but no idea how old they are. He did say that to his knowledge it hasn't been wrecked and that the trans was rebuilt. I have no problem handling maintenance and repairs, I keep my fleet and most of my family's on the road. I've been lurking around here for a few years researching issues on the '02 but decided to register and ask for some knowledge.
