Just to throw this out there, I've been working on cars for 40+ years, motorcycles and bicycles for part of that time. I've no interest whatsoever in vintage bikes, even though I own a couple older ones. I'm so tired of wrenching on crap I rarely even clean my newer bikes. My mtb has sat with a flat for weeks and it needs a new drivetrain.
I'd love to go buy a new road bike and a new mtb today, and sell off some others cheap.
