Question: Which car, produced by Ferrari from 1962 to 1964 for homologation into the FIA's Group 3 Grand Touring Car category inspired the Vandenbrink GTO?
Context: The 1986 Australian Touring Car season was the 27th season of touring car racing in Australia commencing from 1960 when the first Australian Touring Car Championship and the first Armstrong 500 (the forerunner of the present day Bathurst 1000) were contested.  It was the second season in which Australian Touring Car regulations were based on those for the FIA Group A Touring Car category. Group GT3, known technically as Cup Grand Touring Cars and commonly referred to as simply GT3, is a set of regulations maintained by the Fédération Internationale de l'Automobile (FIA) for grand tourer racing cars designed for use in various auto racing series throughout the world.  The GT3 category was initially created in 2005 by the SRO Group as a third rung in the ladder of grand touring motorsport, below the Group GT1 and Group GT2 categories which were utilized in the SRO's FIA GT Championship, and launched its own series in 2006, the FIA GT3 European Championship.  Since then, Group GT3 has expanded to become the de facto category for many national and international grand touring series, although some series modify the ruleset from the FIA standard.  By 2013, nearly 20 automobile manufacturers have built or been represented with GT3 machines. The Vandenbrink GTO is a limited re-bodied version of the Ferrari 599 GTB Fiorano.  This means an entirely new coachwork, designed by Michiel van den Brink of Vandenbrink Design, is fitted on the stripped chassis and drivetrain of a Ferrari 599 GTB production car.  The car's styling is inspired by the 1962 Ferrari 250 GTO as a tribute. The Australian Super Six Touring Car Series, known originally as the Australian Saloon Car Series, is an Australian motor racing series for drivers of Group 3K Saloon Cars.  The Saloon Car category was devised as a low cost amateur sedan racing formula which would potentially replace the ageing HQ Holden category.  The original regulations were focused around large Australian sedans of early 1990s vintage with eligibility limited to VN and VP series Holden Commodores and the EA and EB series Ford Falcons.  The regulations limited the cars to six cylinder versions rather than the V8 engined models, as the latter might make the category too similar to Commodore Cup.  The cars are slightly modified from their road going versions, with an emphasis on safety for racing. The 1969 World Sportscar Championship season was the 17th season of FIA World Sportscar Championship motor racing.  It featured the 1969 International Championship for Makes, which was a series for FIA Group 6 Prototype Sports Cars, Group 4 Sports Cars and Group 3 Grand Touring Cars and the 1969 International Cup for GT Cars, which was restricted to Group 3 Grand Touring Cars.  The season ran from 1 February 1969 to 10 August 1969 and comprised 10 races. The British Touring Car Championship is a touring car racing series held each year in the United Kingdom, currently organised and administered by TOCA.  It was established in 1958 as the British Saloon Car Championship and was renamed as the British Touring Car Championship in 1987.  The championship has been run to various national and international regulations over the years including FIA Group 2, FIA Group 5, FIA Group 1, FIA Group A, FIA Super Touring and FIA Super 2000.  A lower-key Group N series for production cars ran from 2000 until 2003. Group 5 was an FIA motor racing classification which was applied to four distinct categories during the years 1966 to 1982.  Initially Group 5 regulations defined a Special Touring Car category and from 1970 to 1971 the classification was applied to limited production Sports Cars restricted to 5 litre engine capacity.  The Group 5 Sports Car category was redefined in 1972 to exclude the minimum production requirement and limit engine capacity to 3 litres.  From 1976 to 1982 Group 5 was for Special Production Cars, a liberal silhouette formula based on homologated production vehicles. The 1985 Australian Touring Car season was the 26th season of touring car racing in Australia commencing from 1960 when the first Australian Touring Car Championship and the first Armstrong 500 (the forerunner of the present day Bathurst 1000) were contested.  It was the first season in which Australian Touring Car regulations were based on those for the FIA Group A Touring Car category. The Ferrari 250 GTO is a GT car produced by Ferrari from 1962 to 1964 for homologation into the FIA's Group 3 Grand Touring Car category.  It was powered by Ferrari's Tipo 168/62 V12 engine. The 1968 World Sportscar Championship season was the 16th season of FIA World Sportscar Championship racing and featured the 1968 International Championship for Makes and the 1968 International Cup for GT Cars.  The former was contested by Group 6 Sports Prototypes, Group 4 Sports Cars and Group 3 Grand Touring Cars and the later by Group 3 Grand Touring Cars only.  The two titles were decided over a ten race series which ran from 3 February 1968 to 29 September 1968.
