Value is subjective I suppose, if you really like something you'll pay. I've always believed a product is worth what the buyer feels it's worth. It's all perception.What is the bottom price for a running Harley? Obviously an old sportster with stupid ape hangars isn't as desirable as a Fat Boy, but I would be surprised if the bottom was below two or three thousand (for a potato bike, I could see V-rods following import prices as they are desired by a different market).
Old Honda CBs for example, I really like those bikes but don't see the value in them at current prices.
Personally I don't care for Harleys (with a few exceptions) and wouldn't buy it for any price, but someone might think that 2-3k is insane money for a bike like that. Someone else might think 5k is a steal.
