I don't usually rate places online but I'm making an exception for the honest, hardworking crew at AC. I moved to Philly in November 2010 and tried a couple of places before giving AC a shot. It was a good call: I've been consistently impressed by the prompt service, the reliable and affordable prices, and above all the honesty and integrity. These guys work to accurately identify the problem, they won't charge you for guesswork like some places do, and they'll tell you what they're seeing. That's hard to find, and that's why I tell people who ask for a mechanic recommendation to head over to this spot. It's a gem.
