As others have said I have sold plenty I never thought I would so nothing is safe but my 1989 Saracen Tufftax has been with me a while and is a keeper due to it not really being worth much so I may as well have it in my garage. I would say my mint 1992 Clockwork but I often think keeping such a beauty in my damp garage not being ridden is a shame.
Easy decision for me. My beloved Hercules Titanal that was the first frame that I built myself at the age of 16. Hard earned money went into it. And many happy moments I had on it. It woud be the last to go.
Now that I think of it, it is time to take it for a spin right now!
