LONDON, UK - A 1935 Alfa Romeo 6C 2300 Pescara Spyder that competed in the Mille Miglia and was once owned by Benito Mussolini will be auctioned early next year.

The stunning dark red two-seater carries an estimate of £600,000 to £800,000, according to Fleet News, a UK fleet management magazine.

The car was built to the special order of Benito Mussolini.

Before delivery he had it modified with a dickey seat and the engine was specially tuned to deliver 95bhp rather than the 68bhp of the standard model.

The car even retains traces of the partial alcohol fueling system it is believed to have operated during the Mille Miglia, when the fascist regime was promoting the use of alternative fuels in the face of stringent petrol sanctions.
