The business model is actually a total con. Google them and read all the stories of how people were conned out of money, or sometimes even just had the held deposit stolen from their credit cards with false claims of damage to the vehicles. Ended up being told I had to pay an additional fee over over twice the original booking, while letting me know I would have to wait until morning to find another company and even then if any cars are available the short notice means it'll be just as expensive anyway. Felt totally manipulated and robbed. I also witnessed them con two other people while in their offices. One was a young family who probably would have had a harder time adjusting to their plans being ruined after landing at the airport, looked to be getting charged an additional fee of over £1000 pounds to have the rental they already paid for given to them. I wouldn't believe if it I hadn't witnessed it. Never ever use them.
