Super convenient that I could book an appointment on their website at night when they were closed. Got my complete brake pad and rotor replacement done the next day. The total was $290, which is a really reasonable price. Shout out to Adrian for keeping me posted and texting me as soon as the car was ready. Definitely my new go-to mechanic in Fredericksburg, VA
