I know where you are coming from Rex, but as my remaining bikes will never come up for sale it is irrelevant.
I have left written instructions and advice, plus an extensive history. It's someone else's problem when I'm gone.
But I agree I do gloat over prices asked for bikes which were always mediocre, as my star bike was a freebie. Even more so as when I go it, the local VMCC mob sneered at it,as 'it'll never be vintage boy' [its 1938] while still trying to con me out of it, [I was 19 when I got it]
It was the same with my 1936 Levis 350, which I wish I'd never sold . not vintage boy, swap you this stodgy flat tank 350 side valve for it.
There are some bikes beyond price, that 1938 bike was how I found my missus, got me into writing part time, took me all over France several times and much more. How do you value good memories?
Cash then is irrelevant.
