I agree that you should look at a a car in person however if you cannot due time or distance or whatever ask for LOTS OF PICTURES. I mean pictures of EVERYTHING that you want and need to see. You'll find out pretty quickly that a lot of sellers will not send you additional pictures and trust me there's a reason for this. If the guy seems honest and is giving you the info and additional pictures that you request that's a good sign. Also DO NOT GET CAUGHT UP ON ONE CAR. If the deal isn't right there will always be other cars that will come up for sale.
