Some Words From OUR Happy customers

“I have been taking my auto to Northside now for about 4 years. Each and every time they have fixed my car with excellent results. They are very open and very fair with their prices and what is most important to fix first for safety. I would recommend them 100 percent!”
5 star review from Nancy Smith
“Pulled into their shop at 4:00 on Friday afternoon and these folks helped us get a engine issue resolved so we could make it back home to IL. Thank you for being honest and fair. Definitely recommend them and appreciate their sincere ability to make things work for us.”
5 star review from Janet Smith
“If you're looking for a trustworthy mechanic, Northside Automotive is the place to go. The staff is friendly, and any work we've had them do is always done right the first time. We really appreciate having them so close by.”
5 star review from Jody Smith
“Northside provides excellent and timely service. They identify the problem, communicate clearly with me about it and my options and provide lasting solutions I can count on. Can't recommend Northside enough!”
5 star review from Amy Brehm
“10 stars. Honest and friendly. There are always going to be a couple of bad apples that no matter what you do, will give you a bad review. Never had a bad experience and I have been going here for 10+ years.”

The Team

Welcome Northside Automotive

Northside Automotive opened its doors on August 15th, 2005. At that time there were only three bays with two lifts and one drive on rack. The office was an empty shell and the electricity came in on an extension cord. The phone lines weren't finalized so the incoming calls rang through on a cell phone. The first few jobs took a little extra time; as we soon found parts and supplies that were needed to get the jobs done. After many quick trips to Carquest and calls into the utility companies the building started to take shape. In April, 2011 we added another 2400 square feet to the building adding a larger parts room along with updating and adding new equipment. In 2017 we upgraded our alignment machine and drive on lift and moved their location in the shop. In 2019 the front Office was remodeled to make for an inviting place for customers to wait. In 2020 the tire machines were upgraded. Technician training is always at the top of the list here at Northside. Over the years, procedures and processes have been tweaked and fine-tuned to make for a more efficient, well-oiled machine.
