Single owner collections go under the hammer in London

3-litre twin-cam Super Sports 1926 Following the success of last year’s £2.6 million Bonhams sale at the National Motor Museum during the Beaulieu Autojumble, the Motoring team is preparing to return to Hampshire on Saturday September 8 with another eclectic line-up that features lots from three different single-owner collections.
Leading motor car consignments for the auction are two Sunbeams – a 1926 3-litre twin-cam Super Sports (estimate £130,000-£160,000) and a 1912 Coupe de l’Auto replica (£90,000-£120,000).
