I reckon that has to be one of the worst feelings in the world - walking outside to find your car has gone. The little bastards.
I had mine robbed a couple of years ago from right outside my house at uni. My nextdoor neighbour spotted it about a week later abandoned by the side of a road a few miles away. It had been absolutely ragged until it ran out of petrol, to the point that the clutch had practically gone, and the head gasket had blown.
The police were pretty good though, they went up to it and lifted prints and took the fag ends that had been stubbed out on the floor. Then a couple of months later I was informed that they'd nabbed someone for it. Turns out, they'd matched DNA from the fag ends and hair to someone that they already had on file. What made me piss though, was that it was a friggin' girl!!! LMAO
What was the biggest kick in the nuts though, was while the car was in the garage being assessed for the insurance company I was propper ill - had an abcess on my tonsil, most painfull thing ever. They rang to tell me it was being written off, and I just about managed to croak out that I couldn't get down to the garage to get my stuff out of the car, but I'd be down as quick as I could to get it, if they'd keep it to one side.
When I eventually got there, they was all like "huh? what stuff? Fucking wankers. I lost my minidisc head unit, 2x 8" speakers - in enclosure that was in the boot, a few bits n bobs that were in the glove box, and to top it all off, a little gorilla named Gus that was sitting on the dashboard!
Ah well, shit happens...
