Absolutely a garbage mechanic. After bringing my car back to the shop 4 to 5 times to fix the brakes THEY INSTALLED. They actually recommended I take it to another Big O because they had no idea what the hell was wrong with it. The second Big O told me that my brakes were making a strange noise because I needed a new wheel bearing. I took my car to another shop for a second opinion and guess what? They say my wheel bearings are absolutely fine!! But what they did tell me why my brakes is making the noises because my brake Hardware was neber replaced so every time I hit the brakes the old Hardware is hitting the rotor! Nobody ever take your car here even for a simple oil change I'm sure they will mess it up somehow.
