Yup. I got screwed the same way on my Odyssey purchase when I was stationed in Germany. I didn't find out till much later that it was repaired and sold to me as new...(Auto Exchange - BTW).
You should ask the dealer for the customs/shipping paperwork. It should show that they recieved the car in perfect condition from the shipping/transit company or that repairs were done. And in case the paperwork was duplicated after the repairs, then match the dates of the customs-in-country date to the date on the reciept of the vehicle by the dealer. Really shouldn't be more than a week difference.
