When I retired and moved from Maryland to Florida I also needed to find a transporter that would handle my Vettes as if they were their own. Since my '69 is restored, I felt more comfortable looking for a transporter that used enclosed trailers. So, I picked Thomas C. Sunday, Inc. Tom is a Corvette guy and belongs to the Cumberland Valley Corvette Club in PA. Tom was recommended to me by another Corvette friend. Here is a link to Tom's site.

They picked up my Vettes on time and delivered them on time as well. There was not a scratch or chip on them. Tom was not the cheapest enclosed hauler I priced but not the most expensive either. I would definitely use Tom again if I had a need for an enclosed hauler.
Good luck with your decision.
