Buy or hire 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.

Bought where machinery is too wide for the 1.57m GX105HD bed but the shorter 3.03m length is still enough, typically for wider skid-steers and small rollers.
