Well, some of us will remember the Klein advertisement with the Porsche. Others will remember the Bicycle Guide (Bicycling was never a good magazine) article with the 16 pound Klein. So the boron reinforced Klein Quantum may well be a collectable bicycle, someday. If they aren't all, you know, broken by then.

Of course, BF considers a 1983 Nishiki pulled from a Dumpster to be a "collectible" bicycle, so the standards are kind of low around here.
