I have a general rule of thumb when picking out an auto repair shop:
The "office" must be very messy and grease and dirt must be everywhere.
In my opinion, if an auto shop has the time and money to keep a squeaky clean appearance, they're wasting some of your money you pay for service. Walter's Automotive fits the bill with their "office" being a small cluttered desk in the service bay. Their "lobby" is the doorway that you stand in just outside the "office." I couldn't be happier with my first impressions--to me, minimal overhead means maximum service and value.
Sure enough everyone at Walter's is very nice and helpful. Apparently, everyone else in Pittsburgh knows this since I have to schedule an appointment 10 days in advance just to get my car inspected. So please, even though Walter's is awesome, don't come here--I want this place to myself.
