This would have been your colectivo to Quilmes but, obviously, it has a problem. Well, this kind of daily trouble is not rare in a big city like Buenos Aires. Actually, it is not a big deal. You just get off the bus and take the next colectivo that comes, and they are coming frequently. In case of a vehicle defect of line 98 this fancy tow truck comes to the rescue. Remarkably, every bus company has its own auxilio de colectivo, a roadside assistance vehicle. To me, this old Mercedes-Benz truck was rather a roadside attraction. Thankfully, I have personally never experienced a breakdown with a bus in Buenos Aires yet (knock on wood).
