[3] Macri started a home builder, Demaco, and purchased a tiny Buenos Aires apartment facing Vicente López Plaza (in the heart of the upscale Recoleta district).

The 1962 installation of ultraconservative Economy Minister Alvaro Alsogaray, however, and the latter's policy of paying state contractors and employees with worthless "Ninth of July Bonds" led to Vimac's closure.

[5] Inheriting his father's interest in film (the elder Macri had worked for the iconic Cinecittà Studios), he also established MBC, which produced cinema for local directors Leopoldo Torre Nilsson and Alejandro Doria, among others.

Cacciatore had them replaced in 1979 with curbside pickup service awarded to Manliba, a consortium between Impresit-Sideco and Waste Management, Inc.[6] Macri's marriage ended in separation in 1980 (no provision existed in Argentina for divorce until 1987), and in 1982 he married Cristina Cressier, with whom he had his sixth child, Florencia.

The collapse of the Argentine auto industry in 1981–82 allowed Macri to purchase a controlling stake in Sevel Argentina, a local joint venture between Fiat and Peugeot formed in 1980.

The subsequent crisis, which resulted from the implosion of Economy Minister José Alfredo Martínez de Hoz's financial deregulation and strong peso policies, also prompted Macri to take advantage of an exchange rate guarantee enacted by the Central Bank in 1980 for large private borrowers facing sharply higher U.S. dollar payments, a benefit granted to Sevel.

[7] Macri entered into a valuable real estate venture in New York, when in 1979, developer Abraham Hirschfeld sold him a 75% stake in 30 hectares (75 acres) of Hudson Riverfront land formerly owned by Penn Central.

He suffered serious losses during the country's repeated currency crises between 1987–90, but gained from a partnership with BellSouth and Motorola to form Movicom, the first large-scale Argentine mobile phone service provider.

[3] A supporter of La Rioja Province Governor Carlos Menem ahead of his upset victory in the 1988 Justicialist Party primaries, Macri broke from the flamboyant president when, after his 1989 election (which he won on a populist platform), he pursued aggressive free trade policies that undermined Sevel (by then the largest automaker in Argentina) in favor of cheaper imports.

A vocal Peronist, Grosso had reportedly been spared becoming one of the "disappeared" upon his 1978 military abduction only by Macri's appeal on his behalf to Internal Affairs Minister Albano Harguindeguy and Apostolic Nuncio Pio Laghi.

Freed after two weeks in captivity for a reported ransom of US$6 million, Macri's abduction was executed by four members of the Policía Federal Argentina, which has policing purview over Buenos Aires (the perpetrators were located only a decade later).

[9] Sevel, the Socma Group's centerpiece at the time, initially benefitted from the boom touched off by Economy Minister Domingo Cavallo's Convertibility Plan in 1991, seeing its auto sales grow from 30,000 in 1990 to 200,000 in 1994.

[17] His son, Mauricio, was elected Mayor of Buenos Aires in 2007, and in 2008, the 78-year-old Macri divested Socma of two of its most important firms, Iecsa (construction) and Creaurban (real estate), in favor of Angelo Calcaterra, his nephew.

[31] He also received messages from other South American presidents, such as Brazilian Jair Bolsonaro, Bolivian Evo Morales, Paraguayan Mario Abdo Benítez, Peruvian Martín Vizcarra and the U.S. ambassador Edward Prado.
