Our Customers Say it Best

There is no better auto repair shop in the midwest. This is a great group with integrity and customer focus. I very much appreciate them.

Dean Weede

Best place around!! I moved to Janesville 3 to 4 years ago, Patrick is still my go-to! Great and honest work! Not outrageous priced, and his family is awesome!!

Becky Wiedrich

I have used Oneill’z automotive numerous times over the past several years and with each service they have provided great expertise and professionalism. Well done Patrick!

Richard Hill

We were out of town when our radiator cracked and lost all the coolant fluid. We found O’Neillz a short distance away and they quickly took care of the repairs. Cost was fair and honest.

Dave B

O’Neillz is the best. So honest and the work is always done well and in a very timely matter. Thank you to Patrick and your amazing team.

Jane Palmer

Hands down the best place for automotive repairs. Had my jeep renegade worked on. In and out in 4 hours. If I had taken it to kunes. It would have been 3 days, over 13 hundred. Don't go to kunes country for anything. They are sharks 🦈 , will rip you off. Support your small town business.

Jerry Halboth

John Peiffer

Had an engine light pop on. I was able to get in to get that diagnosed quickly and promptly. Found out I needed a new mass air flow sensor and new power steering pump. Pat called me to let me know and he was able to get it all fixed and taken care of for me that same day. My service has always been amazing here and I fully trust that my vehicle is in good hands.

Erika Biksacky

Took my truck there for a alignment and brakes. They did a amazing job. I also got a follow up text the next day asking how everything was. Couldn't ask for better service. I will be going back in the future.
