1974 Datsun 240Z Super Samurai

Sold by Silverstone Auctions, £46,688 

The last time this example of Datsun tuner Spike Anderson’s work appeared at auction it realised £16,100. That was 14 years ago, since when it has passed through various owners but has still covered a mere 5,821 miles. One of the original 240Z Samuris, it was tuned for Modsports racer Eddie Stephens, who bought it as a stock car from its original owner. It was upgraded to ‘Super’ specification after being acquired in a sorry state by Z-car authority James Morris in the late 1990s. The vendor had owned the car for five years, during which time it had been fully fettled and restored.

1994 Leyland DAF Troop Carrier

1990 Norton F1

Sold by H&H, £34,500

Sold by H&H, £28,125

Sold by Silverstone Auctions, £174,375

Sold by Silverstone Auctions, £51,750

1954 Jaguar XK120 Roadster

Sold by The Market, £67,000
