Honestly, they may have lived near Dallas or even up toward OK. My M3 came from Oklahoma, and when I first got it, there was dust everywhere. I have been wiping/washing everything as I go through it. I prefer to work on clean stuff and leave it looking better than I found it. The guy definitely managed to crack a lot of bodywork.Looks like whoever had that bike before you did some dirt track riding. Maybe that's why they crashed.
