Thats how I just bought my bike. Shit I paid $1100 less than what he owed. We had a bill of sale, some other piece of paper that we got from the DMV, I kept his tag(so that I could atleast ride it for a little, and have a little colateral), made a copy of his driver license, and went with him to the bank to pay the balance and send off the certified check. (I also let my sig p245 .45 cal "accidently" show when I got out of the car ) Also make sure you go to there house, not some parking lot. I mean I even met the guys mother so I felt pretty good. But it takes quite some time for the title to be sent out so its pretty nerve racking.........damn I also got everything notorized. I dont play
