You will get a lot of different answers on this one. My enclosed trailer was certainly set up for a longer car. I have heavy ratchet straps like used on a flat bed trailer you would find in the trucking industry. I have to use the hook type, not the flat hook, but a narrow hook. I use one strap on the front, yes 1, by running the strap thru the wheels. I repeat this in the rear. The car will not move. Very simple. They are pulling against each other. I now truck full time and police part time. So, I tie down a lot of things with these straps. Haven't failed me yet.
