New to this forum but not the format as I usually hang out on the BMW sites. With that said, I have the opportunity to purchase my Mother in Law's 2007 GX470 with 135,000 mostly highway miles on it. The vehicle is a former CPO purchase that was fully serviced at Sewell in Dallas with all the maintenance done religiously and documented. My question is, is there anything I should be aware of or ask the dealer to look at before I assume the truck? I have driven this vehicle to CO last winter for a ski trip and it felt pretty solid. Thanks for helping a newbie out.
