When booking your Enterprise car rental at Bristol Airport, keep in mind that there are age limits in place. You have to be at least 25 in order to hire a car and only drivers that are 30 years and older are allowed to hire full size MPVs, luxury cars or vans. If you are older than 75 you also might need to pay an age surcharge fee. There is a special club called Enterprise for younger drivers, so ask your Enterprise dealer for full information on this service.
