1938 Talbot-Lago T150C-SS Teardrop Coupe - chassis #90112

This past weekend, the Concorso d'Eleganza returned to Villa d'Este, revealing such splendid one-offs as the Ferrari Superamerica 45, Aston Martin V12 Zagato and BMW 328 Tribute. But at the same time RM Auctions was holding its first event at Cernobbio, selling a cadre of historically important automobiles we've been following for months, many of which went for multi-million-dollar figures.

1965 Ford GT40 Roadster PrototypeAmong the top sellers were the art-deco 1938 Talbot-Lago T150-C SS (pictured above) which sold for nearly $4.5 million, the rare four-cylinder Ferrari 500 Testa Rossa (sold for just under $4 million), the 1965 Ford GT40 roadster prototype (pictured at right) and the 1947 Bugatti Type 57SC Atalante (each of which went for just under $3 million apiece). The top of the list also included a trio of Ferrari classics from the 50s: a 1955 375 MM topped the list at $4.8M, a '59 250 California at $3.6M and a '53 250 MM at $3M.

Two of the Bertone prototypes that sold broke the million-dollar mark as well – the 1967 Lamborghini Marzal at $2.1 million and the 1970 Lancia Stratos HF Zero at $1 million – while the 60s-era Zagato-bodied Alfa Romeos sold for around $900k and $370k each. All told, some $32 million worth of classics exchanged hands at the event, the full breakdown of which you can find at this link along with more galleries after the jump.
