Old missed opportunity - a green (not Celeste green but grass green) Bianchi from the 1950s - $500 on CL. I call a few days later, was told it sold that same day for $500. Another day passes and someone posts another ad on CL, telling whoever bought that old green Bianchi that they'd buy it from them for double the original price, lol.

Recent missed opportunity - old Legnano road bike $150 - one crappy picture - and hour or so away from me - I wait one day and then it's gone. I didn't really want to drive an hour for it though.

Ya can't buy 'em all!!
