Now in its third year, Salon Privé is the UK’s ultimate Super Car Event and Concours d’Elégance. The three day event offers a unique opportunity to see the most exotic modern and vintage super cars in the world, with the exquisite and exclusive Hurlingham Club as a backdrop. A “Garden Party” atmosphere infuses the event during the day, and in the evenings, the stunning grounds and super cars are subtly lit, transforming the event into a magical spectacle.
