This is one auto repair shop I would totally trust. They are extremely helpful and will only charge you if they actually have to repair something. I purchased a new battery last March. Something must have been left on in the car and my battery was dead. I had AAA charge the battery. Took my car to Preferred Auto. They fully charged the battery and checked the alternator and starter. Even kept it overnight to be sure everything was still ok. I picked up next day and best part...... NO CHARGE. Would not hesitate to recommend them to family and friends.
