- you want one that is 11cm wider inside
Positioned for classic car owners and smaller motorsport teams who want their car fully enclosed and weatherproof but do not need the wider bed of the Race Sport or Race Transporter ranges. The narrower internal width suits a single classic or compact race car rather than a modern GT car.

The CT136HD suits recovery operators, racers and dealers who need a tougher car transporter than the standard CT136, thanks to its heavy-duty beam axles and multi-leaf suspension. Its 4.0m bed and 2.6 tonne gross weight cover most road cars without the cost of a beavertail trailer.
