How to buy a classic long distance

I purchased my B-body off of ebang in 2011. It was listed 2000 (AZ-NY) miles away and being sold privately but the guy was working out of a dealer who specialized in Vettes. The gentleman I was purchasing it from was a NY transplant so we had a small bond. All sounded good. At the time there were a few bids but you could still "buy it now" and if you used that it would include shipping. There was also insurance through PP. Everything was looking good but I was still nervous. I checked the business out on BBB. OK. I then contacted the local police department and asked about the business. All Good. I pulled the trigger and all worked out near perfectly. Your situation sounds different but do as much homework as possible. Talk to the seller. Ask specific questions and get pictures.
Someone suggested asking for a FABO member to go have a look. There are a lot of guys and gals here that know the trouble spots. Maybe even better than a general mechanic. Avoid cars in the rust belt!!!! Good Luck.
