Haha. It's no mine! Too old and, er, large for one of those. A lot of the sites I take photos at have a lot of gulls about. Often I' presented with a car covered in poo. Oh you can photoshop that out. Nope, you can wash it off...
I'm guessing the cars in the pics above have been abandoned or owners on holiday.
Anyway, every time a bird poos on the car now I have scrambled eggs as revenge!
