Outstanding Experience
Because this is such a wonderful vehicle, I purchased it at the end of the lease. Dan and Russ were incredible in making this a seamless transition. My vehicle was inspected, rims repaired, appropriate services rendered, thoroughly cleaned plus received an excellent offer for new tires. I have been trading for many many years with Dan Ramsdell and his team. This experience is once again reason to make the John Thornton family of dealerships my only source for our family vehicles. Highly recommend this team now, just as I did three years ago. Thank you!!! The lease of my new 2020 Chevy Blazer was flawless. This was the third vehicle that I've leased from Dan Ramsdell. We have worked out the details on this transaction (all three) via email. I took limo from Atlanta airport to John Thornton Chevrolet, they opened at 8am just for me. All documents were ready, I only had to sign them and was our in thirty minutes. This gorgeous Black Blazer AWD 3LT has been detailed, filled up with gas, my all weather floor mats put in place and temporary license applied for tag with requested black license plate frame. Derek Strickland saw to it that everything was orchestrated perfectly and my transaction was seamless and most enjoyable. I will definitely trade with these professionals once again and highly recommend others to visit John Thornton Chevrolet!!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

My experience at Shottenkirk Hyundai has been wonderful so far. Today I came in to test drive a car and thanks to Mike Wilcox I’m going home in it! Mike has helped me make an informed decision- as this is my first car purchase so I’ve had loads of questions. I am extremely thankful for his help. He’s had an incredible attitude alongside expert knowledge and you can tell he loves what he does. Thank you Mike!

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.

Excellent service
I was stressed because the car just shutdown at the red light, however, when I arrived at Pugmire dealership, the Lincoln service had notified them and "Barry" made the loaner tranistion smooth and assured me they would service my car Monday morning. Just being in town for a 10 day vacation, Pugmire and Lincoln Service helped to make my trip to Atlanta **Fabulous**with absolutely no regrets.Thanks Barry, Pugmier and Lincoln!!

Ed. D was our salesman. He was very knowledgeable and was able to answer all of my questions. Ed. D went above and beyond to make sure I was able to get the car I wanted. He found a car at another dealership and brought it to us so that I could take a look at it and make my decision. His willingness to work with other dealerships to get what I wanted was very impressive. He was also thorough in explaining all of the features and details of the car so I knew exactly what I was getting. He was professional, helpful, and friendly throughout the entire process. I would highly recommend Ed to anyone looking for a car sales representative!

I just want customers and Days Chevrolet to know that
I just want customers and Days Chevrolet to know that Brenda Lee is service is an excellent person. My corvette was sent there for repairs and they diagnosed and repaired my car to the same standards when I bought it. She was very nice, kept me posted weekly on how repairs were going. She fought with the insurance company and knows her stuff about specific corvette parts. My daughter was in ICU on life support and Mrs. Lee was very compassionate. She is a Godsend. Very professional. Service person of the year in my opinion. This is what service is supposed to look like. Thanks again!

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.
