I'd forgotten about this till today when I was filling up I used to do it on my w201 and thought I'd try it. Many people may already do it but you can wedge the fuel cap in the pump handle and let if fill your car it will switch off automatically so don't worry about over filling.
Yes I know I lazy but if putting in £80 worth of fuel I can be lazy lol
