Any question answered...

Hi there guys!
I am planning to buy a Cinelli Vigorelli FF. Its used but in really good condition only ridden for some miles , and make it a fixie to move around London (only for rides I do not plan to lock the bike outside :P)

What do you think a fair price for it would be?

This is the actual bike!
In addition can someone recognise if the frame is 2011 or earlier?

thnx in advance.

£300 - £350.
It's 2010 or later
