LONDON.- RM Auctions, the world’s largest collector car auction house for quality automobiles, is now on the countdown to its inaugural sale at London’s Salon Privé luxury car show and Concours d’Elegance on 23rd June, 2011.

The sale, which is only open to British-built automobiles, has attracted fifty-seven stunning examples of ‘Quintessentially English’ cars including some significant collections of Aston Martin, Jaguar and Rolls-Royce automobiles.

Max Girardo, Managing Director, RM Europe says, “What is nice about this sale is that we have selected some genuinely rare and interesting cars and motorcycles while also offering a very comprehensive selection of British marques that represent a wide cross-section of some of the best loved and most keenly collected models.”

The star Rolls-Royce lot is unquestionably the unique and historic 1926 Rolls-Royce Phantom I Experimental Sports Tourer, ‘10 EX’, the first prototype Phantom I Continental to be fitted with sports body ‘torpedo’ coachwork by Barker. This unusually rakish and sporting pre-war Rolls has a fascinating and well-documented history and is estimated to fetch between £400,000 - £800,000. It is fitting that in Rolls-Royce’s centenary year, the iconic British manufacturer is represented in the sale by a total of nine exquisite examples, ranging from an 1924 Rolls-Royce 20 HP Open Tourer (Estimate: £60,000 - £85,000) to a late 1993 Rolls-Royce Corniche IV Cabriolet (Estimate: £58,000 - £70,000). Other Rolls’ highlights include a 1926 Rolls-Royce Phantom I Tourer with coachwork by Smith & Waddington (Estimate: £100,000 - £140,000), once driven by Prince Michael of Kent during a visit to Australia, and a desirable 1932 Rolls-Royce Phantom II Continental Drophead Coupé, (Estimate: £380,000 - £420,000), one of just three produced with attractive Freestone & Webb coachwork.

Now fully rebuilt and prepared by one the world’s leading marque specialists, the car is estimated to achieve between £320,000 - £380,000.

“Aston Martin is brand famous for its well-built, high-performance GT cars, and the marque is currently one of the most collectable in market place”, adds Girardo. “Post war DB cars have, in particular, rallied in value in recent years, and we are truly delighted to be able to offer such a broad spectrum of desirable Aston models.”
