-- Clarence Zabel II

Easy to work with and fairly priced. Thought I needed a power steering pump. Once they got in to replace that, they realized it was a hole in one of the lines. Fixed the right thing and saved me over 150 bucks! Definitely going back.

-- Duke Davis

Helped me fix my car and was always prompt, courteous, helpful to make the right decisions on my car. I felt listened to and appreciated! It’s hard to navigate in this new world, but this is the place I would take my business!

-- Ellen

Haven’t taken my vehicle to a different shop in the last year and don’t plan on changing that. Always trying to get me in as soon as possible. Quick turnaround No grey area. Tells you what it is and what it will cost. No slick talk trying to squeeze more money out of you. Verbatim says “I just want the vehicle to be safe” in conversation after thanking him for his help. Cares about his customers and his work. Highly recommend!!!

-- Newo2

This is the place to go! Dustin is knowledgeable, does quality work and has fair prices.

He has worked on three of our cars and we are extremely happy with all services.

-- Barry Hauerwas

Dustin went above and beyond to get my truck back on the road. It would barely run when it got dropped off and now it runs better than brand new!

-- Zach

I had a great expirence went in for a front end control kit replacement on a 2005 Magnum rt. Communication was clear throughout the whole process, the car fought him tooth and nail the entire time yet he still got it done in a very timley 2 days. He also noticed that the power steering rack and steering column was replaced and installed off center so they popped that off and reinstalled it centered at no extra charge which was extremely helpful, I didnt know it at the time but looks like one of the struts is leaking too, so i will be back to knock that out and get those replaced too. I definitely trust Juniors. Super solid!
