RC:

I once saw Bill Gates' 959 at Werk 1 in Zuffenhausen, he had an accident and the car had to be repaired, incl. some major restoration work too. This was years ago...

You can get the accident history of a car over here (if the accident is reported anyway). If you crash on a track there is no requirement that you need to tell the police about it. You often hear of high end cars being sold in "mint" condition that have been repaired after a serious shunt. Is there a requirement in Europe that all body repair is reported to someone?
