It’s raining Rolls Royce today on auctions and how! After the vintage Phantom, it was the turn of a Rolls Royce motorcycle, a 1929 Brough Superior to be brought under the hammer. Auctioned by Europe-based H&H, the 1929 Brough Superior SS100 located at The Haynes International Motor Museum has become the most expensive in the world now! The SS100 was said to be the fastest of its time and was limited to just 29 models. Set with an overhead valve 1000cc V-twin engine, which delivers 45hp, the motorcycle was sold at $455,400.
