I had a similar situation when I sold my Talon. We decided it would be better if he got a ride up here and temporarily registered the car in NY and drove it back.
Unless he’s going to trailer it from the location you two meet, or you two meet at a DMV, he will need some sort of temporary tag to be able to legally drive it, not to mention insurance. If he’s meeting up with you to “look at it,” it doesn’t sound like he would do this before seeing it. So I’d see what he’s willing to do and how serious he is about the car.
My suggestion, tell him everything wrong/right about the car and get him to agree if it is as described then he will take the car. I’d ask for a deposit and tell him it is refundable if everything was not as described (which it will be). Then you two can work out the logistics of transfering the car.
