Lucas, krista Lisa and Graham, were fantastic and helped ne through a hard time after my car accident . I couldn't be happier with my 2017 civic , its fantastic too.

I came across an ad for my dream car, a loaded Camaro 2SS. It was also at CMH 500km away (I live in Ottawa). After reading dozens of reviews and researching a bit further, I took a chance and spoke with Adam over the phone the next day. He answered my questions, and I made arrangements to drive up to see the car, took a test drive, and a week later i came back to drive it home. High praise to the team at CMH, especially to Adam and Krista! Knowledgeable, helpful and a pleasure to do business with. I felt like I was taking home a brand new car. They took much care to ensure everything was taken care of. It’s been about 3 weeks and I absolutely love my car, no regrets, and would happily recommend speaking with Adam if you are in the market for a quality used car.

My wife and I visited the dealership and had the opportunity to explore all the available options. Thanks to Sam’s experience and knowledge, we were guided toward the vehicles that best aligned with our needs. He took the time to answer all of our questions and showed great dedication throughout the process. Thanks to his professionalism during the test drive and his honest advice, we feel confident that we chose an excellent car that truly meets our expectations. Sam clearly puts the customer’s needs first, and we really appreciated that.

Have you ever gone to buy a car and the moment you saw it you knew it was the one? That’s what happened to me when I went to CMH. I recently purchased a 2024 Chevrolet Malibu LT. Lucas and everyone I talked to at CMH did everything they could to make me happy. From the moment I test drove the car to the moment I signed everything fell into place. Thanks again for a great car buying experience!! Aaron Winterhalter.

This is the best place to buy a car hand down! I have never had such a good experience as I did with CMH. Right from our first contact with Adam he was amazing! He listened to us and was very kind and helpful and we got the perfect car! I would definitely recommend him to everyone I know! Sandra in the finance department was also amazing to work with! We walked out of there with all of our needs met and 2 VERY HAPPY people! We were on cloud nine the rest of our day THANK YOU VERY MUCH ADAM & SANDRA
