J & J Automotive Service and Repair LLC

John and the whole team were incredible! With my daughter just starting to drive, I wanted to make sure the car was in top shape—and they really came through. It’s such a relief to have peace of mind knowing everything’s running smoothly. Super quick turnaround time and very affordable. Huge thanks to everyone there!

An honest mechanic(s) is no oxymoron at J and J Automotive Repair and Service center in Medford. I suddenly had major electrical issues with my vehicle and John was upfront about his experience with the type of problem I was having and realistic about the time frame. I thought that taking it to the dealership would be my quicker option, but I was wrong. They not only were unable to resolve the problem, they suggested it was struck by lightening and I get insurance involved because it was too complicated. I then had it towed to an automotive electrician who claimed it was fixed after a week, but did nothing but apply a bandage.

Nothing was wrong with my car, but the mileage was getting up there and I thought I'd be safe and get the spark plugs changed before the long drive.

Not only that, but the mechanic both installed the wrong kind for my vehicle and over torqued it bc it was cracked. $300 down the drain and

Awesome people, John very knowledgeable; fixed all the dealerships “technicians” mistakes. My 6.7 powerstroke won’t go anywhere else. Highly recommended, can’t say enough.

As a Medford neighbor, it's great to support a local business. John and his team at J & J make it easy, because they do a fantastic job, provide immeasurable value for your hard-earned money, and consistently deliver work well above what you'd receive at the dealership. I trust all of my cars to him, and recommend him to everyone that is looking for a reliable and trustworthy automotive expert.
