Someone buys an expensive R version of a bike. Tracks it, removes all the safety wire, then park it for so long they forget what model it is.Because, sometimes it's legitimate. Like a replacement frame. Other times, it could be a stolen bike. I would like to think that the seller doesn't know what they're doing. They just put "No Keys, No Title, No VIN." No Explanation. Doesn't have to give one. But, It'd be nice to have one.
Steals a bike without knowing what it is and the heat keeps it parked to the point the plastic mirrors decay.
