Car Delivery companies are either bespoke car delivery businesses or they are recovery companies making use of the equipment that they already have. Bespoke car delivery companies are usually a little cheaper as they do not have to have as much heavy equipment and overhead to cover. However, there are many more recovery companies out there so finding one will be easier.
Always use heavy duty (Typically 5 tonne) Car Recovery Straps. Light weight straps are simply not up to the job of securing a heavy car to the trailer in the event of emergency manouvers.
