Choose the A Transporter (A4) if...
One of the most common car trailers in Britain, bought by trade and private owners for moving road cars, project cars and small vans. The reason it sells is the spread of bed length and gross weight combinations, which lets you match the trailer to the tow car rather than the other way round.
A range rather than a single trailer. Bed size and gross weight vary together across the model codes, so confirm the exact variant before relying on any figure.
Full specifications →Choose the CT136 if...
The accessible end of car transport, for towing a road car, a track-day car or a small classic. Motorsport and classic-car owners tend toward the twin-axle and HD versions for the higher gross weight and the tie-down provision.
Three gross weights on the same bed. Match the gross weight to the vehicle you actually tow, not to the bed size.
