Local Service and Repair of Mercury Vehicles

At J-N-J Auto Service in Phoenix, AZ, we're passionate about servicing Mercury vehicles. Owners of quality Mercury vehicles in the area have a great alternative to the dealership service department when they come to us for all of their repair and service needs. No matter if the job at hand is a basic oil change or a major engine rebuild, our team here is up to the task. We are proud to stand behind all of our work and will make sure that your vehicle is always in the best condition possible when it drives away from our shop.

The reason that we can stand behind our work so confidently is because of the team of certified technicians that we employ. Our team is the best in town, and we will work hard to care for any model Mercury, including the Milan, Grand Marquis, Mariner, Mountaineer and more. With many years of experience under our belts, it is unlikely that you will find a more qualified shop in the area.

Regular maintenance will keep your Mercury vehicle healthy mile after mile. Over time, your engine will wear and fluids will need replacing. If you provide your car with what it needs through our service, you will be on track for a long and reliable life from your Mercury. Getting the most out of your investment means coming in for regular service, and we make that process as easy as possible. Come in today and find out what you have been missing!

5-star review by Danniel Keyley

"I felt my trucks front end was needing some attention. And realized it needed immediate attention when I saw the right front tire was starting to wear a hole in the fender well. The turnaround was less than 24 hours, price very reasonable. I've been using J-N-J Auto Service for a while now. They are my shop of choice. My truck is riding as it should once again."

5-star review by Pamela Jenson

"I called at about 11am for an oil change. They said come right in. I did. And an hour later I was on my way home. They were very friendly and reasonably priced. I will go there again. It was clean and I could watch my truck being worked on in the bay on the TV in the waiting room. I will recommend this place to everyone."
