A Formula One car that was "forgotten about" in a warehouse for almost three decades is expected to fetch more than $9 million at auction.
The 1954 Mercedes-Benz W196 was driven by five-time world champion Juan Manuel Fangio.
The German-made car contains many features innovative at the time, including a fuel-injected engine, lightweight chassis and improved brakes.
Racing historian Doug Nye said: "The first time I saw this car I needed oxygen. It's landmark technology and it was driven by a landmark driver." The car, unveiled by auction house Bonhams at its London sale room, will be sold in its current condition with noticeable blemishes and dirt.
