drive my car (which is for sale)? My insurance has a limited coverage for out of policy drivers. I've never ever sold a car before, but is it ok to ask for proof of insurance ?

It's not only fair, but it should be expected!

good luck selling that car...ha,ha.

I don't see why not.

sure, you can ask to hold their license, too

but if they wreck your car, and they don't have insurance, you can just sue them for the value...
