Mark, for reference, I bought an identical bike two weeks ago for $4,000. It shows 53k, but has been totally restored by a local well known airhead specialist.
There is a conundrum in the purchase of an old vehicle with very low miles on it. First, as we all know, it does no good for a machine to sit idle for 36 years. But the real problem is that you'll pay a premium for the low miles, which means that if you use the bike that premium immediately evaporates. I doubt that the real price will increase much in the near to mid future. So, if you're an investor and won't ride it, or if you want an original, then this is probably a good price. If however, you want to ride it for several years and then sell, you'll lose big on the deal. (just noticed that the bid is closed, so either you have it or not by now. If you missed this one, good luck on finding another - they are great fun.)
