A rare Aston Martin car once owned by actor Sir Peter Ustinov is up for auction and could fetch as much as £1m.

The Aston Martin DB4 Series IV Vantage Convertible was made in 1962 – when Aston Martin was owned by Huddersfield industrialist Sir David Brown.

It was delivered to Ustinov that year at the Montreux Palace Hotel in Switzerland.

It is one of only nine produced in left-hand drive and will go under the hammer at Bonhams largest Aston Martin sale at Aston Martin Works at Newport Pagnell in Buckinghamshire on May 9.

Also up for sale is a right-hand drive 1962 Aston Martin DB4 4.0-litre Series IV Convertible which could go for as much as £900,000.

Among the other cars featuring in the auction is a 1952 Aston Martin DB2 Drophead Coupe, which was originally owned by Prince Bertil, of Sweden, and which could fetch £300,000.

Altogether, more than 50 cars and 170 lots of automobilia will be on sale.

Bonhams UK head of motor cars Tim Schofield said: “This year’s sale features a selection of significantly rare left-hand drive Aston Martins from the era of David Brown – Aston Martin’s former boss after whom the DB models were named.

“At the time, only a small number of left-hand drive models were produced by the luxury marque, making the models incredibly rare. This year’s sale – in which more than a quarter of cars are left-hand drive – is very unusual indeed.”

Sir David Brown, who also headed David Brown Tractors at Meltham and David Brown Gears in Lockwood, bought Aston Martin and Lagonda Ltd in 1947.

The DB5 – perhaps the most famous Aston Martin, which was driven by Sean Connery as 007 in Goldfinger and Thunderball – went into production in 1963.

Sir David sold the company in 1972. The businessman died in 1993, aged 89.
