The eBay bike that this thread started on, if you were into these bikes I could see the closing price being reasonable. All the original sheet metal to work with, no fiberglass, no major parts to chase down. Plus no hashed original paint to feel guilt about blasting off. Perfect pile of parts for someone who wants to do a full resto on one of these little guys. That being said, it still seems like a heck of a lot of money, but there's a lot about this hobby that's pretty irrational if you examine it too closely.
Cheers, Geoff
