A sensationally patinated 1928 Mercedes-Benz 36/200 S-type topped the results at the Bonhams auction at the Goodwood Revival.
Fuelled by a superb back-story, with one-family ownership for 84 years, bidding for the car rocketed to £2.8 million against pre-sale estimates of £1.5 million.
The Mercedes led a clutch of million-pound-plus sales, all for pre-war cars.
The ex-Giuseppe Campari Alfa Romeo 8C-2300 – below, in its last ownership for nearly 60 years – amassed £1.6 million, the ex-works 1939 Lagonda V12 Le Mans team car (above) £1.2 million and a 1929 Alfa Romeo 1750SS just shy of £1.1 million.
It wasn't all about the big money lots, though, and there were plenty of reasonably priced buys for the shrewd enthusiast.
