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."
