I use them exclusively....
any range of open multiple car carrier to a single enclosed transport! very personalized service and attention to detail! always use them for my GN transport, and have sent many referrals to them.
Don is the man you are looking for...him and his wife run this
I used an open transport to move an f body from sc to az paid $600. I'll try and dig out the info when I get home. f body was a roller. only complaint was the driver was too scared to back it off the upper level so I had to do it @ 11:00pm with no light.
The one I liked was Able Autotransporters, inc. Since the f body didn't have a transmission they required a tow truck to be at the pickup site incase it was needed to load. Call me if you need the #, they are on the web though.
