Looking to purchase an XTS. Found this GM Buyback that the GM dealer told me had interior noises. Headliner was loose, and has been reattached. I asked him to email me the history on the car, but he has not. It is a 90 mile round trip visit, and I would rather make a trip like that to purchase, not look at. Is it possible to get any insight on this XTS? 2G61U5S33D9107720.
