Choose the Race Box if...
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.
Full specifications →Choose the ProLine Beavertail if...
The ProLine Beavertail suits owners of low-ground-clearance cars, since its beavertail ramp lets a car drive on and off without grounding, unlike a flat-bed transporter. PRG offers it across twin and tri-axle chassis so buyers can match the trailer to a 3000kg or 3500kg tow limit.
