Buy or hire the A-Max 305 if...
- you want one that has a bed 1.19m (4ft) longer
Suits owners of larger saloons or estate cars who have outgrown the shorter A-Max 210 but do not need a full car-transporter range trailer. The extra bed length and payload give more margin for a heavier road car.

Buy or hire the GD105 if...
- you want one that is rated 100kg heavier gross
The same market as the GD85 with about 60cm more bed length, which is the difference between fitting a load and not. Landscapers and anyone moving long materials or a quad choose it for the length rather than the payload, which is unchanged.
