Colonia Buenos Aires is a colonia of the Cuauhtémoc borough located south of the historic center of Mexico City. This colonia is primarily known for its abundance of dealers selling used car parts, and an incident when six youths were executed by police. About half of the colonia’s residents make a living from car parts, but these businesses have a reputation for selling stolen merchandise. The colonia is also home to an old cemetery established by Maximilian I, which has a number of fine tombs and sculptures.
