The company is called Green Motion, and the store is not located at Gatwick Airport. To pick up the car, you need to wait at a designated spot at the airport for their shuttle to pick you up. When picking up the car, they will charge a deposit, but employees will never inform you clearly (they just hurry you to sign a rental agreement). During the rental period, if you get a ticket, besides paying the fine to the government, the rental company will charge an additional £68 handling fee for each ticket. Note, this is £68 per ticket! Sometimes their handling fee is even higher than the fine itself. Be vigilant everyone—this is a real lesson.
