I guess the real topic here is transporting a race car. That being said, last week I stopped off at a used school bus lot. Not sure I'm maybe fond over the finished look, and one would need some fabrication skills, but with a diesel real truck air ride chassis, converting it to an RV, and an enclosed car hauler, with always the possibility of hauling a second race car. or an errand vehicle, I liked all the options. School buses appear to be become obsolete (seat belts, crash protection, etc), rather than worn out, are seldom if ever overloaded, likely are run empty 50% of their mileage, are well maintained, never driven hard, are rather plentiful, and come in all sizes. Biggest downside, to me they are seldom high or over powered.
