New and used 2026 GMC Sierra 2500 trucks for sale near Norcross, GA

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.

Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

Kenmanuel Carrizales fue nuestro sales advisor y nos dio un excelente servicio, nos ayudó muchísimo y nos facilitó toda la información necesaria, si van a comprar les recomiendo preguntar por el! Quedamos muy contentos, gracias Kenmanuel

I had a great experience, everyone was friendly and helpful. I got the car I wanted despite being a first time buyer, with limited credit.

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

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!

Benjamin and the sales manager was very helpful. They walk me through the process. Got me approved with very little down.

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.

Giving thanks to the staff, they assisted with identifying the issues and gave alternatives for financing payment. Do to circumstances out of their control wish repair cost was more reasonable...overall pleased with service.

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

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.

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.

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.

The best seller, el mejor vendedor, excelente atención, el deal estuvo increíble, muy feliz con el trato que nos proporcionó

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.

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.
