Repair facilities that specialize in one area of service are gaining popularity. Common areas of specialty include brakes, mufflers, tires, oil changes, alignments, transmission repairs, or electrical problems. Specialized repair facilities can sometimes save you money due to the volume of business that they complete in one specific area. For example, facilities that specialize in tire replacement may purchase such large quantities of tires that they can pass the savings on to the customer. Technicians employed by specialty shops can become extremely skilled in one area of the automobile. They also only have to buy and maintain the tools that relate directly to their specialty.
