There were only ever 21 Lamborghini Miura SV models originally built for the U.S. market and on the 14th of May, one of these rare cars will be auctioned off by RM Sotheby’s in Monaco.

This particular Miura SV was originally assigned to Lamborghini importer Bob Estes but was later reassigned to Alberto Pedretti and delivered on June 18, 1971. Chassis number 4884, this was also the very car that Lamborghini used images of for promotional material and for the SV’s brochure.

After touching down in the U.S., the car made its local public debut at the 1971 Boston Auto Show and after the event, was sold to its first owner, Jack Robinson from Kansas. The Miura SV was sold in 1977 with 12,275 miles (19,754 km) under its belt and remained in the collection of Dr. Alan Brown until his death in 2005. The car was then purchased by Joe Sackey who sent it to a Miura restorer in California where it was thoroughly restored and even equipped with original seat material from Bertone.

Since landing in the hands of the current owner in 2015, the car has been imported to Germany and also underwent a cosmetic and mechanical reconditioning at the cost of €170,000 (~$183,000) in 2017. During this process, the engine was disassembled and refurbished with new bearings, cylinder liners, valve guides, timing chains, gudgeon pins, air trumpets, and piston rings. The carburetors, alternator, oil pump, and water pump were also overhauled while the transmission was equipped with a new clutch, bearings, and synchronizers.

A number of components made the Miura SV stand out from lesser variants, including the upgraded 3.9-liter naturally aspirated V12, the lack of “eyelashes” around the headlights, flared rear fenders, and tweaked taillights. Worldwide production was capped at just 150 units.
