Our vehicles are credit hire vehicles not courtesy cars.
A courtesy car is a car provided free of charge, usually by the repairer or dealership and is likely to be what is available at the time.
AX provide a temporary replacement hire vehicle which does incur a cost, but we pay the charges upfront, which is why it is called credit hire, and then recover the costs from the at fault party's insurer. Also see what is credit hire.
All our FAQs and documentation refer to "hire vehicles" rather than courtesy cars or vehicles for this reason.
