The Story of Precision Auto Service Began in 1984 with the Simple Idea that Vehicle Owners in Tucson Needed a Trusted Source to Service and Repair their Cars: An organization they could trust to work quickly and efficiently on their vehicles. An organization with highly trained, top-rated techs, that specialize in their brand of car. An organization that would maintain their new car warranty while saving them money. Precision Auto Service is "The Alternative to the Dealership" in Tucson, AZ.
