A vintage Aston Martin DB5 driven by Sir Paul McCartney while The Beatles shot to international fame is expected to fetch more than £300,000 when it goes on sale tomorrow.
Sir Paul ordered the dark blue sports car in 1964 on the eve of the band's world tour and had it fitted with a black leather interior, Motorola radio and it's very own record player.
The Aston Martin is one of 93 classic cars going under the hammer at 6.30pm tomorrow in an auction in Battersea Park, London, that is expected to bring in £18 million and £20 million.
Peter Wallman, who will be co-running the bidding for RM Auctions, said the fame of both the car and the owner made it a particularly special item.
Mr Wallman said: "I'm not going to predict that happening here but if somebody collects Beatles memorabilia and just really wanted to have Paul McCartney's Aston Martin then it could go crazy."
Sir Paul bought the car at a particularly important juncture in The Beatles' career, coming just weeks after the band's appearance on The Ed Sullivan Show in America and the completion of filming A Hard Day's Night.
The Aston Martin DB5 was delivered to the musician's accountants when it left the factory in 3 July 1964 and became a regular feature of Sir Paul's 1960s lifestyle, according to contemporary records.
It is believed Sir Paul eventually sold the car in 1970, having racked up 40,513 miles on the clock, according to service records. He has owned a number of other Aston Martins since.
