I bought my 70 Satellite convertible from across the country. I had an inspection done, cost me $300. Inspector drove the car, put it on a lift, sent me about 200 pics and gave me a detailed report of every aspect of the car. When I got the car, it was actually better than I expected based on every little flaw the inspector listed. Then I used a 3rd party escrow service. I wired them the money, they notified the seller they had the money, the seller sent them the title and released the car to a shipper, I took delivery of the car, i notified the escrow company I was satisfied, they released the money to the seller, he got the money and told the escrow company to release the title and they sent it to me. At every step of the transaction, both seller and buyer were protected. Cost 2-3% IIRC. That's the only way I would do it if not in person.
