Like many other experienced endurance and sports car drivers of the era, Galvez only took part in his home Grand Prix in Buenos Aires during the 1953 season. In view of the chaotic and catastrophic course on a Maserati A6GCM, he finished fifth there. The 40-year-old did not contest any other Formula 1 races and thus joined the crowd of all those talented drivers of the 1950s who wanted to try their luck at least once in this class of motorsport, which was new to them, especially the first was the regular "Grand Prix" for Argentina.
At the beginning of his career, Galves Juan Manuel Fangio was considered equal in his home country. For several years (1947–1948) he was the Argentine champion of “all classes” and won the “Especiales de Carrera” in 1949 and the “Turismo Carretera” from 1953–1954. But in contrast to Fangio and José Froilán González , he could not enjoy the support of the dictator of Argentina, President Juan Perón , which meant that the way across the borders of South America was financially blocked for him.
