Choose the A4 Transporter if...
The A4 Transporter suits driving schools, small dealers and enthusiasts who need to move one car at a time behind a car-derived tow vehicle, offering a straightforward twin-axle bed without the cost of a beavertail or enclosed body. Its compact size makes it easier to store and manoeuvre than the longer trailers in the A Transporter range.
Dealers listed this model as 'A4', '130 A4 Transporter' and 'A Series'; all point to Brian James' A Transporter range, where the 4.5m twin-axle bed (model code 130-4520-30-2-12) is the version generally sold as the A4.

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.
