If my car was ever stolen I wouldn't want it back.
I wouldn't want mine back if it's been stolen and yes I would want to run the thieving scum over and then again just to make sure haha car theft along with a host of other crimes are not really a priority any more for the police. sad but true.
Aye, a few years ago a mate of mine parked up at home after work and left his keys in the door, which also had his car key on as well. He went upstairs, heard car doors slamming, an engine start, and a car wheelspin off... After getting that sinking feeling, he shot downstairs only to see his car in the distance. "Unfortunately" he got his car back, complete with petty internal damage and a trashed alloy, but he cut his losses, made good what he could, and traded for a new one because he couldn't stand driving it.
I always keep my car key separate from my house keys for that very reason.
