I haven't personally been to court, but my brother has. He paid some guy several thousand dollars to make some modifications to his car, (paint job, aftermarket part installation, etc.) and the guy basically took the money and didn't do a thing to it after a year. So my brother went to the guys house and took the car back and is now taking that guy to court.

It hasn't happened yet, but from what I've heard my brother has a good case.
