Not everything it returning to one's childhood.
I'd love to get a Cambio Corsa based bike. If I found the right bike at the right price. And, nope, I didn't have one as a kid
Part of the appeal would be the unique engineering. And, of course the value has to do with the rarity. How many survivors are there? A few hundred? A few thousand? The number of bikes that Trek produces in an hour?
