The ultimate auction for Porsche fans: Rare, exotic and dilapidated models spanning 50 years go under the hammer (and there's even a tractor)

If you have a penchant for Porsches then this upcoming auction will send you into a frenzy of air-cooled, Targa-topped, flat-six celebration. 


It's the Porsche Club Great Britain's sale taking place on October 15, at the Silverstone race circuit in Northamptonshire, and it features some of the most collectible cars the German brand has ever created. We've picked our 25 favourites, covering cars from 1959 right through to 2010 with a few surprises along the way.
