We use a hydraulic tilt trailer when buying/transporting cars, makes loading the cars up very easy. The Daytona is too long for the angle though so we have to use ramps/boards to clear the nose properly. I would definitely love to upgrade to an enclosed trailer though, keeping it out of the weather/flying debris is a massive plus in my eyes.
I just pirchased a 2005 f450 bulletproofed it has almost 400k miles, it also has the ramp bed with hitch to pull my cars also and let me tell i absolutly love it just drive up my car to it and be on the way.
A lot of people make the mistake of putting the car in an enclosed trailer and never checking on it , only to find that a tie down has broken or loosened up allowing the car to move around and causing damage to itself . Most of the trailer inner fenders are tall enough to make contact with a rocker panel on your pride and joy .
