+1.u haul or penski have nice open trailers for rent.
I used a U-Haul open trailer to take mine to a dealer 3 hours away. I had never trailered a car before and it was not very difficult. The hardest part was finding a trailer within 50 miles of my house (gotta reserve EARLY). They have a good website and demonstration video on how to attach the trailer and how to load low-clearance cars. Pick up a couple of 2 x 8" boards to raise the ramps so nothing scrapes and try to park on a slight incline while loading. The trailer has its own tie-down tire straps that worked great.
