They are a bunch of scam artists. I rented a Luton van with a tail lift. When I returned the van they claimed I scratched the underside of the tail lift. This is the part of the vehicle that lays down on the ground so you can roll your loads onto it to lift it up to the truck. It is in regular contact with the ground. This is akin to them accusing me of getting a pebble stuck in the tire treads. They are now trying to charge me 1000 GBP for the "damage". I know of three other people that have similar situations. I will never use this company again, nor should you.
