My entry level road bike cost about the same as my used car, but I ride it more than I drive. My old MTB was a gift, and the only $ I put in to it were road tires and $20 computer form Target.
The thing is, other than cooking and wasting time on Facebook, it's my only hobby, and one of few vices (wine and chocolate are cheap). It's cheaper than a personal trainer and therapist.
When people ask what I paid I smile and say "I ride quite a bit."
