$10K for a bicycle is absurd and stupid. I ride an '84 Pug that I bought new. IIRC, I paid a whopping $189 for it, that was guite a step up from my Pep Boys 10-speed and UO-8 Pug. It's still going strong. It still gets me from point A to point B and back again. Not a bad investment for 35 years of pleasure. I'd be willing to bet heavily that that $10K bike won't last close to 35 years. But hey, it's your money and who am I to tell you how to spend it.
