Master Muffler and Brake located in Provo, Utah is an excellent car repair shop. All their auto body workers are very friendly, and knowledgeable. No appointment is needed, you can just drop your car off, tell them what you need done, and they will get it done. It will be done in a very timely manner as well. One time I took my car there to get it repaired and they even let me look underneath my car with them so that I could see what was wrong with my car. Unlike some car repair shops, Master Muffler and Brake is very reasonable priced. My repairs have ranged from $50 to only a few hundred dollars. I would recommend Master Muffler and Brake to anyone that I know!
