I drove down to help Dad move his stuff out of the Economist building: he's finally retiring after twenty-five years or so at the paper. Five minutes from his house the exhaust fell off my crappy grad-student Rover Metro. We tied it on with plastic ties and continued. That night, the car got nicked. Not hard to do as the boot was also only closed with ties.
That has to be the least profitable car theft ever, man. The value of that car was probably negative.
Eventually we persuaded the police to take the crime report, despite them trying to persuade me that the car wasn't registered in my name on their database (it was). I don't expect them to catch the criminals or even recover the car, I just wanted them at least to acknowledge that a crime had happened.
