Hell if it doesn't sell and I don't fix mine up, I'll buy it. My bad luck is such that I'll put mine up for sale, then yours will be gone! Unfortunately, that's the only way I could swing it...I am one of the proletariat
I have Hagerty as well. I was always under the impression that if I was not the one driving the car the insurance policy is void. So, with that in mind if I let someone drive it and an accident occurs or it is stolen I'm screwed. So I read their policy and it turns out that there is this statement where they will not cover us: "Loss to "your covered auto" as a result of anyone causing you to voluntarily part with it as a result of any trick or scheme". So I would say if you let someone else drive your car and they dissapear you are probably in trouble not because it is a trick or scheme but because you were not driving the car. Personally, I would never let someone just take off on a test drive with one of my cars during the selling process. More importantly, good luck with the sale. I have been debating selling mine, but things are so screwy right now.
When I was selling my M-B 450SL I got an email from a guy in Israel who expressed serious interest and wanted to schedule a test drive. OK, I thought, here's a car that has to cost more to ship than to buy and probably attracts crippling import duties. So the guy has to be a flake, right? In fact, he not only showed up, he bought the car! With Benjamins! Turns out he's a pilot for an Israeli cargo carrier and the dispatcher owed him a favor, so he got to send the car home for free. And he said he had more to worry about from his wife than from the customs officers. So you never know.
