Jaguar XKC 018 history

The car, XKC 018, was displayed at the 1952 Belgium Auto Show and was sold to Fangio in October, 1952 through through the Belgian Motor Company. It was the only C-Type specified in bronze metallic, over silver trim. Fangio’s name appears in early-dated Argentinian documents on file, as well as on a copy of the car’s Experimental Department road test report dated October 1st, 1952. As Jaguar typically only sold these to famous drivers, the Argentinian Jaguar distributor, Jose Millet, wanted to obtain one for racing, but Jaguar was limiting sales to famous drivers. So Millet used Fangio as an intermediary to obtain one. Regardless, Fangio couldn't have race it as Maserati declined to allow their new for 1953 star driver Fangio to race in a rival’s car.

Millet had the car repainted in red and white and it was first raced in June 1953, at the Autodromo General San Martin, placing 3rd. Sporadically used in local races, in 1954, 1955 and 1956, XKC 018 participated in the 1000 Km of Buenos Aires, the Argentinian round of the World Sports Car Championship, although the car was never able to finish the race due to various mechanical issues. By 1956, the C-Type was starting to get outclassed by the more powerful and advanced Ferrari 375 and Maserati 300S, pushing Jose Millet to sell her on to another Argentinian racing driver, Jorge Magnasco, who briefly raced it in further local events. By 1961, after passing back through the hands of Jose Millet, XKC 018 had been sold to Ernesto Tornquist who had the car painted in a similar blue colour to the by then famous Ecurie Ecosse cars.

The car remained in Argentinian ownership right up until 1983 when it was purchased by American collector Bill Tracy of Virginia. It was common for European race cars, in the Land of the Pampas. to suffer ignominious fates, gaining strange engines and even stranger bodywork to keep them competitive on ever-smaller budgets. This was not the case of XKC018, as Tracy remarked that the car was kept in remarkably original and intact condition. Tracy embarked on a ground up restoration, repainting the car in red (again) and using it sparingly over the following 14 years.

In 1997, XKC 018 was sold to ex-Scuderia Centro Sud racing driver Giorgio Acutis who returned the car to its original bronze paint and entered it in the Mille Miglia.
