Our Reviews
Overall experience was great from the warm greeting at the door, meeting our salesman, test driving and even finishing up with financing. Larry had us in and out of there in no time at all. Very knowledgeable and explained everything about my purchase. I would buy here again.
I purchased my 2022 XT6 from Hennessy in Dec 2021. Purchasing a new vehicle during the pandemic was challenging. Katy and Thaddeus made the buying experience seamless. They were both knowledgeable and professional.
I had the pleasure of accompanying my sister as she purchased her replacement vehicle. The car buying experience was simply phenomenal. My family was treated like royalty. Thaddeus and the team went above and beyond for my sister.
Mr Roland boughton was great he made the experience easy and relaxing he was knowledgeable on every question I had and he didn't stop until I was happy with what I was getting.
Dealt with sales associates Quinn Lewis and Vick Atefi in the purchase of my Cadillac. Both were very helpful and professional and this was a big factor in my dealing with Hennessy opposed to a different dealer. Post purchase both these guys have been very helpful in educating me on the various systems of the vehicle as I have posed several questions. These guys made dealing with Hennessy a car buying pleasure.
Very welcoming since arriving at the dealership. The sales person Thaddeus McDowell has very helpful throughout all the process but also Cathy, the manager, was extremely helpful also and very condescending. Will definitely do business again with them!
Began discussions with Roland, a very friendly and competent salesman. Completed purchase with Felicia Jones who guided my wife and I through the various steps to finalize the purchase. Felicia is a credit to her profession.
Hennesy Cadillac went above and beyond to make sure I got the vehicle I wanted! The salesman Steven Song really went to bat for me. Steve worked over time and showed he not only cared about the sale, he cared about me the customer as well. Chi’s the general sales manager as well as the General Manager and the finance guy all went above and beyond to make sure I got the best deal out there. Hennesy has definitely earned my business as a loyal customer.
Marcelin Holloway worked very hard to get us the 2021 XT5 we was looking for and we are pleased. His hard work made car buying easy for us. Thanks and looking forward to working with you again.
The process at Hennessey was great!! Best of all was the sales consultant Reggie Batts , he was awesome to work with!!! Top of the line!!!!
We recently purchased a 2020 GMC Yukon from Hennessy Cadillac. It was an exceptional buying experience. Our sales consultant, Reginald Batts, was outstanding. He is professional, courteous, efficient, and fair. Reginald had the car waiting for us when we arrived and appraised our trade while we test drove the Yukon. Reggie was knowledgeable regarding the many features of this specific SUV and readily shared the information with us. When it came to buying the car, there was no pressure. I enjoyed the give-and-take exchange with Reginald as we negotiated the value of the trade. I highly recommend you work with Reginald if you visit the dealership. Final points, we were able to quickly complete the purchase/paperwork with Chib in the Business Office. Chib provided us with a competitive price on an extended warranty for the Yukon. I have been purchasing cars for many years. Our experience with Hennessy Cadillac and Reginald Batts ranks up there with the best.
They are customer friendly I would rank Hennssy Cadillac I10 Star. Very much respect was given. The team that worked on my behalf mr. Chris Adelshine the finance manager went beyond for me andMs Felicia Jones. The sales and leasing Consultant was Awesome and Caring I’m Very happy with Both of them
I had the best car buying experience at Hennessy Cadillac in Duluth Georgia!! Mr. David Bush and Mike Allen was born to be sale consultants. I tell you what they know there craft. They both treated me with so much Courtesy . It really felt like I been knowing them all my life if you decide to shop with Hennessy Cadillac in Duluth Georgia Ask for Mr David Bush or Mike Allen you will not be disappointed. Thanks a million for all that you all have done for me on purchasing my truck !!! By the way I love my Truck!!!
David Bacchus took great care of us - went to trade in 2016 XTS and drove off in a 2020 XT6! David was very patient and knowledgeable, showed us several options and was very helpful. We continue to happy Hennessy customers!
I had a great experience at Hennessy Cadillac and Mike A. was a wonderful salesperson. Very knowledgeable and helped us get in and out the door quickly. Highly recommend!
Wonderful experience, I would recommend purchasing your next vehicle from here. I have had a prior experience with them and was very happy. Mike Allen is very friendly and most important very patient with my many questions. He is knowledgeable and will get the right fit for you.
Purchased a 2020 XT4 from Hennessy Cadillac. They had very competitive pricing. Picked out the vehicle online, Katy Franks, sales manager confirmed it was still available. When we arrived at the dealership Terrance Faison and Chris Adeshina did an excellent job taking care of my wife and I. Good overall experience. If there was any negative from our experience it was the wait time to finalize the paperwork. The dealership was so busy customers had to wait their turn to finalize paperwork.
What started out as a trip to for service ended in the purchase of an XT5 Cadillac. Service writer Shannon Moore did an excellent job with the service then introduced me to David Bacchus who sold me the XT5. Both gentlemen did an excellent job. David was very knowledgeable and helpful during the sale. What started as a new car inquiry ended up with the purchase of a preowned XT5. Great job by both men and the dealership.
If your in the market for a Cadillac David Bush is your guy. A true professional!!!! Second vehicle ive bought from him in 2 years. Best experience ever!
My experience with my sales rep Carl Morrison at Hennessy Cadillac in Duluth, Ga was a wonderful and amazing experience. He made sure that they made me an offer to seal the deal as well as making sure I was comfortable. The test drive in my new Cadillac CT6 Luxury was incredible. I highly recommend this dealership and Carl Morrison to anyone! Thank you Carl for being the best person you can be and for my new cadillac!
I’ve always had great success here. Courteous, professional, and always communicating with me. Shannon is the best. As long as Shannon is there my cars will be serviced there
Shopping at Hennessy Cadillac was a great experience for us. David B. really went above and beyond to explain the vehicle's features, what to expect from the vehicle, how to install features such as Onstar and pairing my phone. We are very satisfied with the customer care and the facility was top-notch. Everyone was friendly and accommodating. I will surely recommend my sales agent and this dealership to my friends and family. Over-all, we are happy with our purchase. We will surely come back for maintenance to see how the Service Department compares with the Sales.
I had such. A great experience at Hennessy. I worked with. Greg Simpson. He was so knowledgeable and personable. What a great experience. I would definitely recommend others to your dealership and I will tell them to ask for Mr. Simpson.
After a rocky initial visit with a different sales consultant, I can’t say enough good things about my experience with Daniel Roland (internet sales) and Donald Wooten. Don stayed late on a Thursday night, well past close, to ensure we had a smooth sales process. He went up and beyond to make sure we had a good understanding of all the vehicles features and even took the time to take a family photo with the new ride. Genuine and authentic - which is not what I tend think of when it comes to a sales consultant. I would highly recommend anyone in the market to see Cadillac Don!
Great experience. Nice sales staff. Made car buying enjoyable. Not pushy at all. very knowledgeable about products and services. Would recommend to family and friends.
