My bike eventually hit the reserve and sold for £500. I had hoped for more, but I think £500 was fair. It's gone to a good home and the buyer is happy - seemed perfect for what he wanted.
So now, as someone helpfully pointed out, I have a full licence and no bike! I've been tracking a few on ebay but so far nothing has been right.
This would seem like a good time to end this weblog. I've achieved what I set out to - pass my bike test so I'm happy.
Thanks for the advice and encouragement, it honestly helped.
