Customer Testimonials in Stillwater MN
As part of replacing the cabin air filter, the tech disconnected the coolant line which goes to the coolant expansion tank but failed to reconnect it. As a result, as I drove home roughly a half gallon of coolant was sprayed all over the passenger side of the engine compartment and the underside of the hood, and puddling on the garage floor.
Fortunately I possess sufficient car knowledge to locate the open line, reconnect it, and replace the lost coolant. I then cleaned the engine, the underside of the hood, and the coolant dripping onto the garage floor.

Amanda Deustch took care of my financing while I was going through an active Chapter 13 bankruptcy. She got me exactly what I needed. She was so prompt with her responses and answered my questions with great detail. I could not have had a better experience. She is the best!
Thank you for prompt sales servicing with Mark Cosgriff with Cornerstones Motors! We are completely satisfied with Mark and our new vehicle?
The process of buying my truck and trading in my old truck was a very pleasant experience, unlike I've had at other dealerships in the past. Everyone involved, from my salesperson Oscar to management and finance, was extremely helpful, polite, and professional. I will gladly work with Cornerstone of Stillwater in the future.
Been coming here for years to buy and service my vehicle’s. Love the way they support the community from the local food shelves, youth sports and the chamber. Keep it up.
Thanks for the great work and within the timeframe. Nice job Wes and body shop crew.
Helped me get exactly what I wanted. Jim is knowledgeable and straight to the point.
Jim Boening in sales made my purchase so easy and enjoyable. He was helpful showing me all the new features of my new vehicle. He is a top notch guy!
We went out of our way to go to cornerstone Chevrolet in Stillwater. They responded quickly and they had what we wanted. So pleased we made the drive. Working with Isaac Anderson was a pleasure.
NICHOLE SERVICE WRITER CARES ABOUT THE CUSTOMER NEEDS AND CONCERNS. SHE NEEDS HER NAME ON THE GLASS AT HER DESK WITH 5 STARS. DON B
Cornerstone continues to impress me. Mike Kahn is a great general manager - he is honest and communicates well. Isaac A. treats his customers with phenomenal professionalism and follows through with details and questions. A great experience!
Corey M, is the greatest! He makes it so easy to buy a vehicle. He is helpful, knowledgeable and goes the extra mile.
Katie Little reached out to me to offer information in regard to a 2026 Trailblazer I was interested in purchasing. She gave me great information and invited me out to see the vehicle.
I met her and she gave me a great tour of the vehicle and facility. After speaking with her I knew she was the right person to work with for this purchase.
Once we got the Trailblazer information taken care of and the sale arranged I asked her about the 2025 Z71 RST Silverado that was displayed on the floor! She showed the vehicle and explained all the details ... Read More DealerRater - Sep 15, 2025
Jeremy and the technicians at Cornerstone do. Great job with service and repairs. The only problem is that they are so busy becuase word got out abothe quality of their work it's sometimes hard to get an appointment with them without waiting a week. A good problem to have but it's tough when you only have one car. I do wish they were open later but I understand staffing is difficult when you're that busy due to gokd work.
Over charge, over charge!! When Stillwater Moters was in you were treated fairly, but not Cornerstone Chev of Stillwater. (same places)
My wife and I have bought many cars over the years, but this was by far our best experience. Corey and the staff there made the whole experience easy and stress free. The vehicle is great and they have helped us since in many ways.
From the staff in service and in the body shop to finally in sales everyone was very friendly, professional and helpful through a difficult car accident experience. The assistance in what to expect with the insurance process to be able to purchase a new Carin the way I preferred was importiant to me and evolved in a timely manner. Sincere thanks to all who were involved. It is much appreciated.
Dan R. I recently bought a newer car from CCS and was so impressed by the professional and personal experience I had!! Not only did I buy a car but I feel like I gained a new friend…. I was treated so well and with respect thank you. Nice sales job KT Little!!! Thanks again. If I buy another car there I hope she’s still working there 🙏😎
I’ve worked with the people at this dealership for more than two decades as their customer. The people there are just fantastic. They go out of their way to help you and to solve problems. It’s clear that customer service is ingrained in their culture. I count on them for nearly all of my transportation needs, and they always come through.
Extremely helpful! Very glad that the staff is still there after the new ownership started! Service department is very efficient & makes it convenient to get an appointment.
Well, they did it again! The team at Cornerstone Auto has gone out of their way to make the process of getting a new vehicle easy and professional at the same time. My sales consultant, Troy, and manager Darcy helped me get into a great new vehicle and feel confident about the options and pricing. Tony and Brian made the financing and final details clear and easy. What a great experience!
Customer service was excellent. The communication was open and flowing. She heard us and heard what we were saying. The communication with the technician was available and helped with our diagnosis of our truck.
I purchased an extended warranty, and was told a loaner/rental would be available at no charge for any service I came in for. That was a lie. I'll not be bringing my vehicle back here, even though it's where I purchased it.
Jeremy (service writer), the transport drivers, and the technicians at Cornerstone Chevrolet were fair, honest, professional, and ethical. I'm more than happy to bring my Volt in for service work at Cornerstone Chevrolet.
Quick check in and called when complete friendly service too and no hidden up sells
Salesman (Cory) and finance person (Tony) were both very patient working with an older gentleman (75 years old) who has hearing issues and not being used to alot of the new technology on buying a new car. Everyone at Cornerstone were very friendly and helpful.
They are trustworthy, and care about you and your vehicle . I will be back . Thank you
It was a pleasant experience all around at the dealership. We give a high score to the dealership and especially to our salesman Oscar Rodriguez!
Very Unhappy. I brought my truck in for the Auto Butler and an oil change. When I went to pick it up the Auto Butler was not done. I also stated my concerns about when I'd tried to get service on another vehicle earlier this summer, and no one from the Service Department would return my calls. I have had good customer service with the prior dealership since 1995. This was not a "good customer experience."
Friendly, fast, knowledgeable people . Excellent customer service and all staff is attentive and willing to answer .
Everything went great. The staff was friendly and attentive. Will return when service is needed.
Kevin, our sale person was very helpful in finding the car we asked for. He was explained everything about it. And if any questions to call him. In the leasing department, went very smoothly and very nice person to work with. A very good experience all around.
