I'd recommend a tilt bed if you can find one, I've had them all and they were the easiest to use, especially with lowered cars.
If you get one, I'd be interested in renting it occasionally if you're interested. I just rented a trailer on Monday to pick up a F150 I bought and UHaul wouldn't let me use it because my class 3 hitch on the Tahoe was only rated for 5000 lbs. Needless to say I got another one and it worked good, but was a little small for the F150, the tires were touching on both sides.
