For the purposes of a "new" vehicle, is your concern the warranty and whatnot? I would expect the warranty to be 36,000 miles from when you took delivery - so, 36,689 or whatever the actual mileage is when you do the paperwork. One of the pieces of paperwork will be an affidavit of the odometer as part of your vehicle title process. I'm sure if you had an issue at 36,400 and you got any flak from the service department, a phone call and a copy of the paperwork would solve the problem in a jiffy.
