I agree. I shouldn't have a problem. In the unlikely event that I give them $30,000, $40,000, or more, and oops, they file bankruptcy or decide to take early retirement with my funds, who here will reimburse me? It suddenly got quiet.
I think you are being a little anal about paying cash, since you stated you have never paid cash for a car or rv before.
As for myself, I have never in my life financed a car or rv; always paid cash.
As long as you have the proper paper work completed; bill of sale, title and registration applications, pdi inspection, manufacturers warranty's, etc. Give them a personal check or bank check. Then drive or pull it off the lot.
