I think you need to look the car over quietly and carefully. Only ask what you can't tell by looking. This many questions will quickly become "the car not for sale".

Your first question needs to be about clear title. I don't see that on the list. There's no need to ride out to inpect it without an anwer to that.

I had one fellow selling a car advise cash and carry. I was to pay $17K cash and he hands me the keys. He wouldn't take a cashiers check, not even at his bank. I dropped my interest when we couldn't meet a happy ground. I found out later it was his wife's car, owned solely by his wife. NY was a "no-title" state he said, only a registration. He was selling it out from under her because garage space is premium in NY. I'm glad I didn't end up in that mess.
