STUTTGART.- A rare and fully restored 115-year-old Benz Ideal will be the oldest motor car at the single-marque Mercedes-Benz Sale in Stuttgart, Germany, on 28 March. The annual Bonhams auction will this year feature more than 40 lots of collectors' motor cars.

The Benz Ideal was an early development of the groundbreaking combustion-engined motor car: the Vélocipede (commonly known as the 'Velo'). The impressively restored Ideal offered by Bonhams dates back to 1900, and is estimated at €230,000-280,000 (£170,000-200,000).

Introduced in 1898, the Ideal was designed to compete with models produced by the growing number of manufacturers in the car market at the turn of the century, combining a steel chassis with an impressive 4½ horsepower (1899-1901) single-cylinder engine. It is believed to have been sold new in the U.K. through British Benz Agents, Hewetson's Ltd. and still wears its brass supplier's plaque confirming this.

From its very earliest days, the car was registered in Shropshire, UK, and it was there that it was found in the 1950s. Its discoverers, Ralph Wilde and Jack Moor, subsequently restored the car, and it remained in Moor's family for more than 50 years before coming into the present ownership.

Philip Kantor, Bonhams Head of European Motorcars, said: 'A regular entrant and successful finisher on the London to Brighton Veteran Car Run, this definitive Patent Motorwagen is now 115 years old and going strong – a testament to the strong foundations of Mercedes-Benz engineering.'

Bonhams Mercedes-Benz Sale will take place at 14:30 on 28 March in the Mercedes-Benz Museum, Stuttgart, Germany. The Mercedes-Benz Museum charts the entire history of the world's oldest car manufacturer, with a total of 1,500 unique exhibits featured in the museum.
