Initially, cars weren't repaired through one service. They had 5 areas (Oil, Engine, Brakes, Suspension and Tyres, I believe), All deteriorated at different rates and could be serviced individually and the number of cars being seviced at once wasn't limited. I think when they switched it to the system currently in place, they introduced mechanics but the people that had been playing before the switch didn't have a set number of mechanics, therefore can service as many cars as they wish, at once.
