The ex-Essex Racing Stable, 1961 Aston Martin “MP209” DB4GT Zagato with the registration “2 VEV” was auctioned by Bonhams at the annual Festival of Speed sale at Goodwood in Sussex.
The auction house said it was snapped up by a European buyer, who has not been publicly named.
A world record for the most valuable BMW ever sold under the hammer was also set at the Bonhams auction.
The 1957 BMW 507 Roadster – previously owned by British racing driver John Surtees – fetched £3,809,500.
James Knight, Bonhams motoring chairman and the auctioneer for the sale, said: “We are simply blown away by today’s results.
“The world records that we set today are indicative of the continued market desire for the historically significant motor cars with impeccable provenance such as ‘2 VEV’ and the John Surtees BMW 507.”
