In the neighborhood around the Townhouse Gallery where I work there are all sorts of auto repair shops. One garage replaces windows, another does bodywork. What is striking is that none of the shops do everything. Each garage is specialized in one particular part of the car. So every screw, the rings, every engine part has its own place. So if you were to dismantle a car and open a garage for every part, you'd have a good impression of what this neighborhood looks like.
