I bought two cars from Mike Barrows.
I bought two cars from Mike Barrows. Mike's salesmanship goes unmatched. He did not pressure us at any point and was always willing to do his best on a price for us. The transaction was quick, easy and smooth. Just to top it all off Mike donates $50 dollars for every car he sells to united for the troops and having two grandparents that served this really blew me away. Thanks Big Mike!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Amazingly knowledgeable, friendly and helpful.
I don’t remember the guys name who ran the diagnostic on my 2018 Chevy equinox- but he was very helpful - even showed concern for our dogs. My turbo froze up- they gave me a quick cardboard piece on the front and sent us on the way- we were traveling to Sturgis from Jamestown and panicked when we lost power- they got us in quickly and took care of us—thank you sooo much!!!
