The current Formula 1 World Land Speed Record car, a 2006 Honda F1, nicknamed Bonneville 400, is estimated to sell for £10,000 – £20,000 at Bonhams Collectors’ Motor Cars sale at Silverstone on 24 July. This superb car accomplished a speed of 397kph on the fabled Bonneville Salt Flats in the USA, setting a new world land speed record for a Formula 1 racing car which has remained unchallenged.

Another important car in this sale is the Datsun 260Z Super Samuri Racing car, the ex Winn Percy car, estimated to sell for £40,000 – £60,000. Affectionately known as ‘Big Sam’, this red and black two door circuit racing coupe got the thumbs up from Tony Dron: 'What a pleasure it is to drive a car that handles really well: it’s easy to see that Winn Percy must have enjoyed notching up his wins… Big Sam is an absolute delight to drive on the track; the 2.4 litre straight-six engine revs freely, feels unbreakable and is safe to at least 9000rpm.'
