Homer's is great. I moved to Pittsburgh a month ago and so far I've brought my car to Homer's twice.
First time I had them check the engine, tires and overall condition of my car having driven 2000+ miles. I also changed the oil and the windshield wipers.
Second time they performed the required PA state inspection.
Both times they were very helpful and effective.
The first time they helped me out by letting me drop off the car the day before the actual scheduled service.
Once they are done they send you a text to let you know that you can go pick up the car.
They charge $73 for the PA State Inspection.
