Last station I worked (lower Manhattan ‘69) didn’t even have a lift, just a pit for oil, lube and exhaust work. Motor work was done outside. Brakes, shocks and front end work were also done outside on jack stands.
You’re right though. Today we have gas stations and we have repair shops. Rarely do we see the two combined. I think the new lifts that did not need the underground pneumatic piston chambers helped separate the two. I knew a repair shop that opened up in what was once an OLD movie theater thanks to those lifts.
