Although not the least expensive, I selected Montway (only a few dollars more) for their most consistant positive feedback. The car belonged to my son, who could no longer make the payments/insurance - so I 're-posessed' the 2004 Mustang Mach 1 for my own use. Montway hired Energy Transportation, Inc out of Las Vegas to handle the transport, which sort of worried me as now I'm dealing w/ a 3rd party and somewhat concerned if something happened to the car during transport (insurance etc). I only dealt with Montway's folks on day 1 and they provided the contact info for Energy Transportation, which I dealt with on a daily basis. They were prompt. The driver was careful to ensure the open roadway access and protection of my and other vehicles on the transport. My neighborhood is full of tree's and a bridge to get here. Energy Transportation did the route planning to discover a weight limit on the bridge and helped determine an alternate drop-off ( walmart lot ).
This is the second time I've used the uship site (first to move my motorcycle) and I find it easy to use, carriers are quick to respond and I like the transparant bidding to keep folks honest and competetive.
I'd use uship again.
