I believe that only the top-of-the-line models might gain collectible status, but I'm not even sure of them.

80% of the carbon bikes today are made in China, in one huge factory. They are all CAD and made by machine, not man. Hardly the stuff of the artisans of the 60's, 70's, and 80's that make steel frames so collectible. I also think they are rather ungraceful and look out of proportion to it's rider. I don't think they're looks will stand the test of time like the graceful, proportioned, almost fragile looking steel frames do.

Top-of-the-line bikes might make it, because they are built in the country of origin, not China. But again, looks are a problem...IMHO of course!
