If it were a press car (strong possibility), then you KNOW it's had the crap kicked out of it by idiot "reporters" (including a lot of the low-end YouTube idiots, who somehow get press cars). I would definitely avoid any such car like the plague!
Do you mean all corporate cars, or just ones that have had the stuffing beat out of them? There's another corporate car I'm looking at with 18k on the odometer, the CarFax looks clean AFAIK, of course if VW was doing the maintenance it wouldn't show up would it?
