Local Service and Repair of SMART Vehicles

At J-N-J Auto Service in Phoenix, AZ, we're passionate about servicing Smart vehicles. SMART Cars are relatively new to the automotive scene. Developed in the early 2000s, SMART Cars weren’t introduced to the United States until 2008. Manufactured by Daimler AG, the SMART Car has an unmistakable compact size and forward-looking design. Fuel efficient and cost effective, these small vehicles are the perfect transportation solution for the modern urban auto owner, proving that bigger is not always better. Regardless of size, you depend on your car day in and day out. As a SMART Car owner, you understand that a quality car demands quality service, so it only makes sense to find the highest quality service for your SMART Car’s repair and maintenance needs.

Our shop specializes in providing superior service to our customers and their cars.

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."

"I took my Jeep Wrangler for tire alignment, and they did not disappoint .

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."
