At least get a bill of sale from who ever you buy the car from. Almost every yard won't take a car without a title or lost title form filled out, and if they do they won't pay **** for it. So what I do is lien sale cars that I don't get a title or lost title form on, there's plenty of companies you can use to file the lien paperwork but I use Speedy Lien based in Corning, CA. Where is your location by the way? I work out of the Chico area in butte county. As far as cutting cars up, that doesn't really seem legit to me, plus it's a ton of work. easier to just file a lien on it.
