Buffo, I disagree with you. It's true what you say, but it happens many times that people buy things on a whim, esp. motorcycles, and they sell them when they are short of money or because they are forced by their families. Well, it can easily happen with old bikes that they have had several previous owners and one never knows what's inside, but I'm of the opinion that, when somebody is careful with his vehicle on the outside -nice paint, clean parts, no dings or scratches etc- it means usually that the vehicle has been gently used and timely maintained.
