These are the best and most valuable collector automobiles on the planet: cars that are rare, limited editions or race winners, and often with fascinating histories or famous owners. But will the super-wealthy turn up to bid? Can these classics hit their multi-million pound estimates or will they fail to reach their reserve price?
