Agreed. Our building is nicer looking and in a nice part of town. This attracts high end customers and scares away low-end customers. If you look expensive, it only attracts customers that are willing to pay for it.
I even test this theory out every time I get a ride in an Uber. Without fail, they will have their TPMS light on, maybe a CEL, and a few other odds and ends wrong with their vehicle, showing that it has clearly not been maintained. They don't know I own the shop, so I ask them, "you ever brought your car to that shop down the road to get that stuff looked at?" Without fail, they always reply, "oh no no, they look too expensive."
