Italian design house Bertone will put into auction six concept cars this May 2011, as ordered by a bankruptcy court. These are composed of three Lamborghini, two Lancia and three Chevrolet vehicles.
Three of these cars have great significance in Italian design milestones, and one of these is the 1967 gull-winged Lamborghini Marzal prototype, which was later manufactured as the Espada. Princess Grace and Prince Ranieri drove the Lamborghini Marzal in the Monaco Grand Prix in 1967.
The second vehicle of significant value is the Lancia Stratos HF Zero, a mid-engined car that went into production as the Lancia Stratos, which dominated the World Rally Championships in the 1970s. Marcello Gandini, an Italian car designer working at Bertone between the years 1965 and 1980, conceptualized the Lancia Stratos and the 1967 Lamborghini Marzal. Bids for these two vehicles range from 1 million euros to 1.8 million euros.
The third high-value vehicle is the Chevrolet Testudo, which was unveiled in the 1973 Geneva motor show. Its designer, Giorgetto Giugiaro, drove the vehicle from Turin to its debut venue. Bids sought for this concept car range from 500,000 euros to 800,000 euros.
The rest of the concept cars have lesser historical significance and thus, will be sought at lower starting prices. For the 1978 Lancia Sibilo, bids are expected to range from 60,000 euros to 100,000 euros, while bids for the 1980 Lamborghini Athon and the 1974 Lamborghini Bravo could range from 150,000 euros to 220,000 euros.
