That's a pretty long trailer. You will need a serious tow vehicle. Just have an extended ramp door put on and you shouldn't have a problem. Remember if you are going to put the car in the trailer without it being hooked up, you will likley need rear supports to extend to keep the trailer from tipping up.
Here is a pic of my trailer. My car is lowered so that I am about 3 1/2" off the ground on the front. I have to put down 2 12" 2x8 because my car is so low, but they are no big deal. The trailer was built for a gen III which was not as low as mine. Had the extended flap been 6" longer I wouldn't have had to use the two boards.
