I recently bid on this speedometer gasket on eBay. It is nos, so that's something to consider. I stopped at $35.00.
The seller is very reputable who doesn't pull weird shit, so that means the final bid was most likely legitimate.
What's unbelievable to me is that it went for…wait for it….US$202.50! Is that part in that condition so rare that it warrants someone paying that much? I know I have, on occasion, paid a lot for a part I really needed, but that seems out of this world to pay that much for a rubber gasket. I don't even think it's ridiculous, but instead fascinating with regards to supply and demand of certain Vespa parts.
Seeing whole bodge scooters sell for $5,000 or even $8,000 doesn't surprise me, but events like this still do surprise me.
