New and used 2025 GMC Sierra 2500 trucks for sale near Buford, GA

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.

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.

Multiple options available, in their lot of vehicles, they treated me very well when I contacted them, they earned a positive rating from me

Hennessy Cadillac is by far the best experience I have had ever in buying a vehicle. This is actually my second Cadillac I have purchased from them and I have nothing but great things to say! From the sales department to service it has been nothing short of amazing. I am not easily impressed but everyone I ever encounter at this dealership handles me with care and respect. Entering a dealership as a single woman could be intimidating but not here! Terrance and management went above and beyond to make sure I leave happy every time. I pay attention to how others are treated and I will say I haven’t seen anyone actually upset even in the service department. The concierge level service of greeting me opening doors all things I expect from Cadillac are given every single time. It is always neat and clean on the premises. And most importantly my deals are fair and respectful. Desmond is usually my service guy and he is absolutely always honest and makes sure I am kept up to date with any thing my truck needs without feeling pressured to buy or upsale anything to me. Even once sending someone to pick up a key for my truck when the other one didn’t work. I went to another dealer recently and found a truck I really liked and test drove that I could have purchased but didn’t because honestly I didn’t get the same concierge service from that Lexus dealership. Hennessy and Terrance made sure all my experiences were top tier. I have owned a lot of cars in my life and have had good and bad experiences on every level but Hennessy has not disappointed me one time. Check them out ask for Terrance in sales and Desmond in service and I promise you won’t be disappointed.

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.

Terrance Lundy did his usual great job - Big T takes care of you! got want we wanted and took care of everything for great experience

Great experience from start to finish. Antonio has been one of the best salesman I ever had. Highly recommend.

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

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

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

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.

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

Amazing attention from kenmanuel carrizales this is the second truck than I get with him nice un clean thank you again

Benjamin has a lot of knowledge on his field, very professional, takes good care of the his customers.

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 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!

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.

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.
