Wants a test drive but no insurance

[Skyedriver]

Currently have my TVR for sale, guy, local, viewed it last week and came back this afternoon for another look.
Took him out in it 10 mile run out, came back and he says "so you won't let me drive it then".
I suggested he could with insurance cover, suggested he had "third party" cover only so I refused.
His response "well I won't make an offer if I cannot drive it" and literally stormed off in an arrogant huff.

Now I don't know him from Adam, he might be a good driver or not, and if he hits another car, or the 4 kids on horses thst we passed, it'll be my insurance that takes the hammer, third party or not, I suspect.

I know I usually want to test drive a car but it seems to be a standard added to adverts nowerdays "no test drives without insurance"

Still he now knows he's rather have a Chimaera than a Z4 and has wasted my time and petrol.

Thanks for your comments, so I wasn't being "unreasonable".
It was his arrogant "well I wont even make an offer if I cannot drive the car" followed by his immediate stride of to his own car and wife.
Hindsight is a great thing but I wish I had said something as he left, you know, about wasting my time and petrol and maybe suggesting where to go next....

And so you ask if he can afford it if he bends it, how would you make him actually pay up, you couldn't surely without a written contract.
And if he's caused an accident with the horses and young riders...
