The chap on the telly this morning said he doesn't normally get the CDW, so was asked to shell out £750 up front on his credit card, to be paid back if he returned the car as he found it (rather than just give credit card details in case of damage). He also hired a car in Belfast, and was asked to pay an extra £11.50 to be checked with the DVLA as he had only brought the pink card and not also the green bit of his driving licence . He just said check the agreement before you hire really as you can avoid these charges.
