I had bought several bikes from a flipper in a near by city. The prices were fair for the condition of the bikes. Somehow he came into possession of a Peugeot. The bike had a fork that was not original to the bike. Also, it had other noticeable flaws. I informed him that the bike had likely been in a accident. Even if the bike was in pristine condition, his bike was substantially overpriced. In an email, I gently informed him of the value of his bike. Although he was kind, it was apparent that he didn't accept my evaluation. Although I was attempting to be helpful, he perceived it negatively. Since then, I have decided to help only when asked.
