Hennessy Cadillac is by far the best experience I have
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.

A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

I came in for oul change and my Rear riverside tire
I came in for oul change and my Rear riverside tire leaking down. it took over 3 hours to complete work. I was grateful that the tire was replaced with a new one., but they did not put valve stem cover back on nor did they clean the white sealant material from around tire and wheel. I think they could have been more customer focused
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Great learning experience
I worked with Brett and Daniel. They both were extremely helpful and informative. Although I did not end up purchasing a vehicle here, they were professional and genuinely wanted to help me find what was best for me. Highly recommend this dealership.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

On 8/23/25 After an exhausting search, we were blessed to
On 8/23/25 After an exhausting search, we were blessed to be connected with Lloyd (Lincoln side) of Hennessy Ford Atlanta. We were looking for a specific used car I saw online (that we learned was located on the Ford side) but our GPS took us to the Lincoln side. The entire process from start to finish went smoothly and Lloyd made sure we felt valued every step of the way. I experienced a level of customer service with Hennessy Ford that is definitely lacking at other dealerships.(If you've ever been to Gwinnett Place Nissan you understand). Even though it was a used car and not their brand, Lloyd still thought it not robbery to call us to see how things were going with the vehicle. Now, that's service! I highly recommend Hennessy Ford and Lloyd to anyone needing a new or used vehicle.They really do care about their reputation!
a great Truck
I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

I just want to say that I had a very professional
I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down.
