Néstor Otero, known for being a crucial figure in Argentina's bus terminal business, died at the age of 78 after experiencing health complications in recent months. Otero cemented his status as the 'Czar of Retiro' through his long-term management of the Retiro Bus Terminal, a vital hub for national transport, operated through his company TEBA S.A. since 1993. He managed to thrive through various governmental administrations despite ongoing concerns regarding the terminal's operations.

His career was also marred by legal controversies; he was convicted in 2015 in a case involving the payment of bribes to former Transport Secretary Ricardo Jaime. This investigation revealed that Otero had incurred expenses connected to bribery, highlighting the murky intersections of business and politics in Argentina's transport sector. Despite the controversies, Otero's influence over the industry remained significant, illustrating the complexities of navigating business, governance, and public service in the country.

Otero constructed a substantial business empire linked to bus station operations and associated services, affecting various public transport contracts across different national and municipal governments. His passing marks the end of an era for the transport business in Argentina, where his legacy will likely spark discussions about accountability and ethical business practices in the sector.
