New and used 2026 GMC Acadia for sale near Cumming, GA

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!

Ben Clark was very helpful in getting me out of a tough situation with a previous vehicle. This is my 2nd purchase through Hendrick and I’m very happy with the service and willingness to help.

My experience was informative and the repairs were completed in no time. I have been taking my car there for 9 years and they still display the same great customer service!

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.

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.

Excellent customer service. Good job. Ben was clear and concise in explaining the process of buying a vechile.

I always receive excellent service from Colonial. Last time they stressed how important fuel injector cleaner is for my vehicle, however this time they didn't mention the cleaner and when I brought it up they said they would take care of that next time. How important is it really? Just left me wondering and thought I would mention it.

Very nice and knowledgeable one of the best experience I’ve ever had at a dealership, hands-down

We have always been happy with the Loganville dealership even before they move from Lawrenceville. Honest and tells you like it really is. They get the work done right and on time the first time.

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.

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

I was looking to upgrade my truck and met Nolan Knox who helped me look for the right truck. He was patient as I tried to make the best decision for me. He responded to all my questions even when he was off. I would recommend Nolan to help anyone with car or truck buying from Carl Black GMC of Roswell.

We purchased a 2025 GMC Yukon from Nolan Knox with Carl Black. Nolan was great, kept us well informed. The purchase was simple and painless. We will purchase our next vehicle from Nolan and Carl Black.
