BMA certified 3 speed - only $500.

And this one is just of personal interested mostly, although the price is way too high (but not comically high as in the above link)

I sold this VERY SAME BIKE (yes this exact 1964 Schwinn Co-Ed 3 speed) two years ago, for $36. Now it's worth $125 - what is inflation coming to these days?
