I think Lee Dahmer, owner of Sterling Replicars Unique Motor Cars Cobra and Intermechanica Porsche Speedster dealers, is now doing car transport. I think he is in the DC or northern Virginia area.
I haven't used his services, but I know he knows the value of these cars. He can be reached at 540-554-2040 or 703-404-0663.
