Rough Norton Jubilee with Navi engine on ebay £3.750.00. A very nice one went for less than that not long ago. Now everyone is asking ridiculous prices for a dogs dinner.
Ebay is full of chancers. There was a thread that drifted onto this a few weeks ago.
Somebody made the comment that rather than make the comment about fools parting with money, they should wonder how the fools got the money in the first place.
At the end of the day though, anything's value is only what someone is prepared to pay to have it.
For fun, I like to look at mototcycle 'projects' with 'sort' set to ending soonest. I never seem to be amazed at what people are willing to bid on.
