"They are without question the best mechanic shop in the area. They're one of the few shops that are honest, fair, and in my experience they usually come in at, or below, their estimate. Riley is excellent at communicating all needed/ completed repairs and is very friendly. I & B is one of the few auto shops that don't leave you feeling like you were ripped off by the time it's all said and done. I recommend them to anyone who asks where to find a good mechanic. Simply put, I & B is a top-notch mechanic shop with excellent staff. A+++"
