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

Jeff was awesome. He kept me informed of what needed to get done and how long it would take.

My experience buying a car at Mall of Georgia Mazda was top notch! Grant Richmond was very friendly, helpful and answered all my questions. I love my new car!

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

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!

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.

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.

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.

Robert was amazing to work with! He helped us find the right Mazda at the right price so we could buy here in Georgia instead of driving to Huntsville. He even arranged custom leather seats in the model I wanted and set me up with a loaner since my old car had been totaled. The whole process was smooth and stress-free — highly recommend Robert and this dealership!

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

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.

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

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

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

As always quality service. Knowledgeable people handling vehicle. Great waiting area and the offer of water. Sales floor could be a little more accommodating to the customers needs.

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.
