Two great experiences:\r
A few years ago I got an oil change there. I'd had my clutch repaired by a competator only a few days before. I left American, drove across the street to the grocery store, and my clutch completely gave out. I called American, and two guys came RUNNING over to the grocery store, pushed my car to pop the clutch and start the car, and drove it back to the shop. They fixed the clutch for MUCH cheaper than the other shop and I've never had another problem with it.\r
Recently I was given an estimate from another shop of about $780 for front struts, alignment, and other work on the front end of my car. American did the repair for HALF that price.\r
They are now the only repair shop I will go to. It's not a problem at all to make an appointment for an oil change.
Pros: great prices
Cons: not a quick lube anymore
