From the young lady, Yammonica who was attentive, on
From the young lady, Yammonica who was attentive, on target and customer focused to the service department and even the lady who took our payment, the response was professional and focused on our needs. The communication was clear, on target and open. Care of the car was terrific. Our expectations were met and even exceeded. We have a car that has been to the dealership before and we will continue to use Mt. View Chevrolet and hightly recommend the service to others. Top rating and no complaints. Thank you
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.

I have been to a few different dealerships in Fort Wayne
I have been to a few different dealerships in Fort Wayne and around the country and every purchase me or my family has made has been the best from Kelley. My most current purchase, 2017 Chevrolet Equinox, was very smooth even though I was not quite ready I could not pass up this deal I got. Jacob and his coworkers were very accommodating and patient.

I recently purchased my 2026 Chevy Traverse from Colonial
I recently purchased my 2026 Chevy Traverse from Colonial Chevy in Acton, and I couldn?t be happier with the experience! From start to finish, the team made everything easy and smooth. Matt was my salesman, and he went above and beyond to help me get the Traverse I wanted, even though they didn?t have it in stock. From Matt to the GM to the finance team, everyone was professional, friendly, and efficient. The process was quick. I wasn?t stuck at the dealership for hours like you often are when buying a car. Since my purchase, I?ve reached out to Matt a few times with questions, and he always answers his phone right away, which I truly appreciate. I would absolutely recommend Colonial Chevy to anyone looking for a great car-buying experience!

3rd time buyer
I had a terrific experience dealing with Kenston now for the third time buying a vehicle. I highly recommend this dealership as they make the entire process very easy and low pressure. Matt was a terrific help to me answering questions and easing the buying process. I ended up purchasing a terrific truck, low miles and every bit as new as driving off the Ford dealership lot. Buy from Kenston, you won’t regret it.
