The team of Sales Dept. and Finance Dept. made my used truck purchase experience a pleasurer. From the time we were greeted until I drove away with a full tank of gas, I was treated with genuine and friendly service. Best of all for me was maintaining a quick pace for completing a transaction, as I had to travel out of state for the sale. Would purchase another vehicle from the team at Hennessy Buick GMC of Morrow, GA.

Great experience with Hennessy of Southlake. Frank Parker was awesome and represented the dealership well. I flew in from Memphis, was picked up from the airport and everything about the car was as represented online.

Thought I got a good price for a good car.. Hennessy has a unique nitch with new cars a year or so old that are priced well. I purchased a Ram Promaster City that was a very good value. I would highly recommend Miguel AND Aaron, Very personable, friendly and did everything you could sk for to make it a good transactioin.

Car buying can be stressful and intimidating, but not here! We purchased a used Ford Transit Van that had a wheelchair lift installed. I had been researching these vans for several months. We drove almost 3 hours to come and see this van after looking at several others that were closer to home. I wish we would have just started here! We worked with Duane and he never made me feel rushed or that we were waisting his time. He was very professional and treated us with respect. We also worked with Gerren in Finance. We had several questions, but never felt silly asking any of them. He was very informative and kind. When we are ready to buy again we will be repeat customers!

The salesman was honest and fair! Process was pretty quick and easy The vehicle was nice and clean and we left with half tank of gas vs the full tank that we agreed too HOWEVER we would definitely do business with Mike again!! Mike was a pleasure to deal with ..... The finance Manager was very nice also, loved how he made us feel very comfortable and how he explained everything.

From making the Appt, which is everything, bc you only have to talk to one person; to the day of the appt, customer service is excellent and you only deal with your service advisor; to the checkout, in which your service advisor takes your payment. Excellent and another satisfied customer. Thank you Marissa Powell and Bob Allen.

We bought a used 2018 Camero from Hennessy in Morrow, Georgia. We did not see the car in person but Christopher Brown, our salesperson, did a wonderful job showing me videos of the car and giving me all the information we needed to make the decision to purchase the car. Chris did a great job from the very first phonecall to the sale and delivery of the car to our hometown in South Dakota. Chris and Hennessy is awesome and we would surely recommend them.

It was an honor to work with Chris Brown and Gerren Terrell. They were transparent, personable, and made me feel so comfortable through the entire process of purchasing my first vehicle. I walked away feeling not only confident in my purchase, but like I completely understood all of my options through the process. Everyone at Hennessy was kind, welcoming, and knowledgeable. If I could give them 10 stars I would.

Best automobile purchase experience ever!!! We received outstanding customer service and the team exceeded my expectation by closing the deal within a couple of hours. Everyone was professional, polite and courteous. I would absolutely recommend Hennessy Buick GMC if you are looking to purchase a new car. Ask for LaMichael Wilkins. Thanks LaMichael and Gerren for making my daughter’s first car buying experience pleasant and memorable.

Purchased a vehicle from Michael Reyes yesterday, he was very helpful. Mike did a good job of keeping me within my budget, with a vehicle in great condition to get myself & my family around. I'd highly recommend visiting Michael Reyes for any future purchases.

I had great experience! The staff was very welcoming, cordial and professional. They were very attentive and assured that I was getting the best deal

I was an “ easy mark “ because of my great experience with my 2008 Mazda which ran for 216,000 excellent miles ! My phone inquiry was promptly answered . It was a big deal because I live in Roswell and am an hour away from the dealership . I had to be real sure that I wasn’t going to be given the “ bait and switch” routine . I wasn’t and our experience was super in every way .
