The 166 MM/195 S that sold for $ 6.5M including premium at Gooding on January 29, 2016 is a typical example. It is estimated $ 6.5M for sale by Gooding in Pebble Beach on August 25, lot 145. Here is the link to the press release.
I narrated it as follows in 2016.
The development of the engine is of paramount importance in the racing debut of Ferrari cars. The model 166 caused a sensation from its release in 1948. This figure indicates the displacement in cc of each of the twelve cylinders of the Colombo V12 engine for a total of 2 liters.
The chassis are sent to subcontractors who assemble the cars as berlinetta, barchetta or spyder. The berlinetta is an early success because it can be used both on road and on track. All the elements that will make the tremendous success of the brand are already in place.
The Ferrari coming for sale is one of the six 166MM coachworked as Berlinettas Le Mans by Carrozzeria Touring. Completed in June 1950, it is first raced in the following month. Chinetti, who is already the agent of Ferrari in the United States, exhibits it at the Paris Motor Show in October for finding an American buyer.
The car is purchased by the sportsman and team leader Briggs Cunningham, after he had applauded the feat of Chinetti topping the early hours at Le Mans in 1950 with a 195S berlinetta. The major difference between 166 and 195 is its bore enlarged from 60 to 65 mm enabling a displacement of 2.3 liters.
Cunningham has immediately upgraded his 166 to the 195 specification by Ferrari. In December 1950, this car has the honor of becoming the first competition Ferrari imported in the USA. A few days later it begins its American career at Sebring.
