I can't see the whole car with the pics you have. I see a bunch of parts a different shots I can't tell what you got base on the pics.
As far as doing a deal with someone out of state. That is something I would look in to. But one thing for sure you can't ship it with out full payment. I think the other guy need to have what you are selling inspected first before you doing any thing else the inspector guy can verify you are the owner and there is a clear title and even take pic for the guy.
As far as your number of out of state sales is not an issues. Hes asking to find out if you have ever sold out of state. So before talking to the guy you need to find out what you need to do to ship out of state. I would say call a shipping company.
