This car collection is expected to sell for over £37million

The headline car is a 1939 Bugatti Type 59 Sports for which auction house Gooding & Co. is looking for £10m plus. Billed as the ultimate Bugatti grand prix car, the supercharged straight-eight works racer won at Spa and was third at Monaco before dominating in sports car racing of the period. Converted for road use, it was snapped up by King Leopold of Belgium and has had only four owners since then. Gooding says it is arguably the most important, original and coveted of all competition Bugattis.

The Type 59 joins two other Molsheim marvels, both just as special in their own way and almost as valuable, with the 1937 Bugatti Type 57S Atalante tipped to make at least £7m. The other Bug in the sale is a 1928 Type 35C Grand Prix (£3m up).

The Bugattis are special but chased in the special stakes by an equally wonderful trio of Aston Martins: a DB4 GT Zagato, a DB3S and an Ulster and together conservatively worth £12m. In any other auction each of them could easily have been the star of the show, as could the Lamborghini Miura, the Rolls-Royce Silver Ghost and Vauxhall 30-98 also in the sale.

Wherever you look in this revered collection is a true automotive great, a testament to the collector’s meticulous passion – so much so Gooding & Co. has called the sale Passion of a Lifetime. It is actually Gooding’s first ever sale outside the US – nothing like arriving with a bang…
