New and used 2026 GMC Acadia SUVs for sale near Duluth, GA

I recently purchased a truck with Ben, and the experience was excellent. He was highly professional, knowledgeable, and genuinely great to work with. I would absolutely recommend asking for Ben—he’s a fantastic salesman. Nathaniel Faulkner

My experience was excellent with Ted. The videos from the technician ere very informative. My son-in-law had a previous car worked on here and also purchased a new one from Ellis GMC.

Very good service from Cato, he was amazing and I am so satisfied.He help me get exactly what I was looking for in a car.

Andres was great and very helpful. Although we didn't purchase we would definitely work with him again. We highly recommend him. He's honest and not pushy.

My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.

Our 2013 Terrain was purchased from Colonial back in 2016. It has almost 222,000 miles on it. Still performing well. We always get great service at Colonial. Kimberly is our service representative. She does a great job. This time was a fluky thing. The only key we had was lost and we had to get a new set of keys. A frustrating situation was made easier with help from Colonial and Kimberly.

Call to about a concern with my check engine light. Was done fast an efficiently was a power train issue and was fixed correctly. Truck is running fine.

Dwayne was our service rep today. He was beyond expectations. He was very responsive and professional, making sure we were kept informed and that we understood the repairs. Great service!

The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

Nolan Knox from Carl Black, Roswell, was so easy to work with in purchasing our new Sierra 1500 denali ultimate. Nolan was so professional and knowledgeable as he answered all our questions. I highly recommend Nolan Knox. Thank you for making this whole purchasing event less stressful. Charles & Deb
