Do you float the titles or just bend over and take whatever arbitrary limit for non-dealer title transfers that the dealers lobbied into existence in your state?
In my state, Oregon, for example, the DMV has agents watching craigslist, facebook, autotrader, etc. who go test drive private party cars under cover and ask the question, "So, why are you selling?" where answering that question incorrectly (along the lines of, "oh I bought it to fix up and make a few bucks") will net you a several thousand dollar fine.
