回複：you bought the rental insurance or your CC covers the rental.

I had tested a lot of cars but just in local not highway because I don't think it is nessasary and safe when I drive a car which I am not familiar with. but I took a car to go to a station to check and send back to dealer at next day and without getting any problem. I will ask them this matter before I test the car.
but I think rent a car and test a dealer car should belongs to same situation just you drive a car which
not belongs to you.
