This one could go either way. Use normal diligence, everything face to face, exchange cash for title and keys at the bank. Not a penny until you've driven it.
I listed a motorcycle for sale on eBay about 10 years ago. Before my auction was even over, a scammer had copied my ad word for word, set up another auction under a bogus ID, and used my pics. I reported them, but the ad stayed up for a couple of days. I went in and edited my ad with my home and work phone numbers and assurance to any bidders to call me and personally talk to me.
Insist on talking to them on the phone and seeing it in person before agreeing to anything.
