He says 65,000 miles. Title says 130,000 miles 5 years ago. A good running 1968 convertible.......35,000 miles in 5 years sounds about right for a car that has been enjoyed. I wouldn't get too worked up over the mileage if it is numbers matching or at least mechanically in good condition. The part I would be worried about is the owner that seems to be possibly covering up 100,000 miles. Personally I would believe the title over the owner. A piece of paper has no reason to lie. A person can gain from a lie. But my glass is half empty when it comes to trusting people selling anything. Ask for receipts that show mileage, anything that can uphold his claim.
