No similarities whatsoever. While I appreciate both bicycles and cars, I have zero desire to acquire an older vehicle. Old cars are nothing but trouble and money pits to boot.

I don't really consider myself to be a bicycle collector either though. To me, that implies that they get zero, or only token use. Although I did get a new bike last year to help me stay ahead of the maintenance curve, I truly enjoy riding my bicycles... all of them.
