Here's one of the replies so far.....
IDEA - i read an article about a guy that had his 911 stolen so he put an advertisment on E-bay under Porsche 911 section ( cars for sale ) with a big sign saying STOLEN. He posted all the details about the car and within 2 days a guy rang up saying he had been offered the car but with different plates on - he had simply recognised the rare factory option alloys fitted and realised that it was that very car. They caught the thief and got the car back.........worth a try ?
