I would like to buy a Bianchi Pista Concept 2005...2009 like this one:
Where can I find this bike in London, UK? And what should I check before buy it?
Also, How much should I expect to pay for?
This is only a partial answer, but the Bianchi dealer locater shows several dealers in London. I'd call around and find out what the ballpark is in terms of cost.
