When Lamborghini presented the Lamborghini Miura in 1966 it was THE sensation. Not only was it ways ahead of the competition from Ferrari (the 275 GTB and the Daytona still had the engine mounted in the front) it was also a century design. Marcello Gandini, working for Bertone, had done a great job. The car was ultra flat and for its time also quite wide. The mid engine developed roughly 350 hp from 4 liters, enough to bring the car to almost 280 km/h for the people being brave enough to try it. In a contemporary test in Hobby people were very pleased by the handling, but 40 years later you would probably rather describe it as adventurous.
The car sold very well, 765 cars were produced and brought money to Lamborghini. Faster versions were produced, i.e. the S, the SV and the Jota.
Miuras have increased in value dramatically over the last 10 years. I remember seeing advertised cars for roughly Euro 200k, today it's rather twice that much for a good one.
It's certainly not a cheap car to own, as mechanically it's fragile and spare parts are sought after. But if you look for THE 60ies super car then this one is the one to have!
In 1986 Bertone celebrated 20 years of Lamborghini Miura at the Geneva Car Show, that's were the second picture is from.
