John Lennon's classic car is set to fetch up to £265,000 at auction. The late Beatles legend's 1956 Austin Princess, which he bought in 1971 and was used in the film 'Imagine', which is based on his album of the same name, will be sold at RM Sotheby's auction house. According to the Irish Examiner, Lennon - who was shot dead outside his New York apartment in 1980 - had some modifications done on the plus motor including the addition of four aeroplane seats. The lucky buyer will also receive the original registration documents with the 'Let It Be' hitmaker's signature. Money raised from the sale of the Austin Princess will go towards charity including Unicef and Make A Wish America. The sale will take place at London's Battersea Evolution on September 7. Lennon left behind his widow Yoko Ono - with whom he has son Sean Lennon with - and son Julian who he had with his first wife Cynthia. 83-year-old Yoko is still making music and has no plans to retire from her art anytime soon. She told BANG Showbiz: "I want to keep on making music and art and keep on inspiring people. But I don't know what my fans take from what I do with my work and my website, I just keep dishing out things and I hope for the best, but I never know how people will react to what I do."
