I firmly believe that something is usless unless it can be enjoyed. If you can enjoy a bike by looking at it hanging on the wall, good for you. I can't. I therefore refuse to own something too nice to use, I'd rather sell it and buy cool stuff that I can ride/drive or whatever. I own a couple of old scooters, a Vespa and a Lambretta. Both would be considered classic or vintage, but neither is so collectable that I'm afraid to ride them. Same with my old VWs. My '70 VW single cab is about the most rare or collectable thing that I would feel comfortable using on a regular basis. Anyway, that's my take on the thing.
