Questionaire - Customization and Personalization

I really like my bikes, for several reasons. But if one was replaced with its cash value tomorrow, I'd just get a new one to replace it, end of.

How could I put a cash value on my Hetchins though?

1 of 90 surviving Magnum Bonums, Dating from around the mid 50s, classic dura ace/campag, and rides beautifully... plus it was me that rescued it from being left in a cellar for the rest of its days.

Don't think I'd sell it regardless - and it's only going to gain value the longer I hold onto it?
