My name is Jack Walton, I’m had the best experience I am
My name is Jack Walton, I’m had the best experience I am 77 years old and Al Gee filled all our needs. Great service,great staff from sales to finance. I would recommend Also Gee, he was s simply the he best. Great salesman.
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.

Special treatment and special pricing.
Todd and his team were outstanding. They found just the right car for some friends of mine who asked me to shop for them. Customer service was exceptional. Pricing was very competitive, and the overall experience was a 10+. I highly recommend that you give these professionals a shot. You will be pleased.

I was able to contact a salesman after hours by text and
I was able to contact a salesman after hours by text and arrange for a viewing the next day. When I finally arrived on Saturday evening my selected vehicle was standing by for a viewing and a test drive. Afterwards we did the paperwork and I was helped by the salesman in making a domestic wire transfer through my banking app on my phone. No cash or checks necessary! Once the wire went through the service department changed the oil, detailed the vehicle and set the tire pressures. I was able to make arrangements for a delivery to my home saving me a trip and several days of anxiety. My salesman kept me informed at every step. The vehicle I chose was in great condition inside and out which speaks to the quality of the vehicles on the lot. I feel like I got quality service even though I didn’t purchase the most expensive vehicle on the lot, by a longshot. I also had the opportunity to purchase a great warranty for my vehicle, which I found to be surprising that it was available at all. I look forward to working with Kearns again in the future for my next big purchase.

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 had a rough first experience at Mac Haik Chevrolet’s
I had a rough first experience at Mac Haik Chevrolet’s service department, but Brian Caldwell, the Service Director, completely turned things around. He personally followed up the same day I voiced my concerns, sent a mobile tech to my house to handle the software update, and later arranged for a porter to deliver a loaner and pick up my truck for a roof recall and additional service. They performed every repair as promised—on time—including the roof fix, oil change, tire rotation, and a minor interior issue. Brian kept great communication throughout, even with our busy schedules, and treated my time and situation with real respect. What started as a frustrating experience turned into one of the best service recoveries I’ve ever seen. Huge thanks to Brian, his team, and Mr. Mac Haik. This is how a dealership should be run.

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.
