Like Oxonian I try to park behind someone with a parking sensor - did this last month behind a BMW X5 and left plenty of room but he/she still managed to damage my number plate!

It's not just p-cars - had pre booked a car park space for my wife's Toyota RAV at Manchester airport for a 3 week stay and got put in prime postition near the terminal building but unknown to us this was a drop-off point for limos etc. We came back to find 34 seperate dings and marks.....

Final bad story - also have a Lotus Elise as a sunny day toy and this car has never even been wet so is like new. Parked at a garden centre and was sitting in the car when a woman driver tried to squeeze a large car into a too-small space next to me and proceeded to hit the Lotus. When I got out to have words(!!) with her she said "Well, you didn't leave me enough room did you"
