A while back I saw a car trailer with a built-in lift. It looked like a normal car hauler except that once the lift was extended, you could walk under the car for easy repair access. Has anybody seen these for sale? Thanks, Jag

 

I think this is what you are looking for.

That's it. I especially like the seat thing that slides down the middle. Any idea on the cost? Jag
