This weekend, Ferrari's 70th-anniversary celebrations are set to hit a fever pitch as the company opens its factory and museum doors to thousands of its loyal clients for presentations, parties, an auction and even a single-marque Concours d'Elegance.

In recent weeks, a host of Ferrari rallies have been taking place across major European cities and on Friday these cars -- some 500 in total -- will be converging in Milan before heading to the company's HQ to complete a lap of its Fiorano test circuit. On Sunday there will be a Ferrari-only Concours d'Elegance where experts will pick the two most extraordinary examples from a selection of 120 of the rarest and most exotic cars ever to wear the Prancing Horse badge.
