I found a Trek 520 on Craigslist. The ad had very little information. The bike was selling pretty cheaply at $200. I asked the seller why so cheap? What is the year? And can he provide proof of ownership. I figured either it is very old or it is stolen (he did mention it was in working order but in need of a tune up). Well the guy freaked out. He said I was calling him a thief.
Do you think it is over the top to ask for proof of ownership when buying a bike?
