Just a GREAT experience from beginning to end!!!!
Today was the day to pick up my car! A week ago, after just a day of discussions, Sammy and Aaron made what had been a terrible mistake I had made a couple of months ago into a WONDERFUL sales experience! And THIS during a pandemic when I was having to try and correct my mistake while sheltering in place at home. You see, I have always driven foreign vehicles and SUV's since 1999. And there have been a lot of them, just never an American car, except for my play Jeep. But, our family needed a larger vehicle and we had decided on a Navigator. In January, we went large and purchased a Navigator. Unfortunately, we didn't go large ENOUGH... We needed a Navigator L to accomplish our needs. You can imagine the pain of this realization given the depreciation that takes place the moment you drive a car off the lot. AND I didn't figure it out for over a month. Well, I had spent almost 2 weeks negotiating with the dealer I had purchased my previous vehicle from as well as EVERY OTHER Lincoln dealer in the Metro-ATL area...All not willing to help me with my problem and at the end of the day leaving me to feel as I was going to have to live with my mistake. Then Sammy called ME! And within one day we had worked out a deal for a trade that I could very definitely live with. In fact, one that I could even be excited about. And the pricing for my trade (granted it was almost new) was done site unseen. AND when I got to the dealer there was NONE of the haggling or you didn't tell us about this, etc. Just fair-mindedness, and during these dangerous times...A SAFE environment! I couldn't have asked for more. And when they needed to do some work (tinting, clear-bra, etc.) work to my new vehicle, I was immediately placed in a wonderful loaner until my new vehicle was ready. SO MUCH Better than my last experience. These guys are doing it right and have earned by service business. Yes, It's a long review, but these guys deserve it. I look forward to meeting my service adviser and working with these guys for years to come! AND I can't wait try the Pick-up and Delivery Service!!!!!

As a proud Cuban woman who values honesty, respect, and
As a proud Cuban woman who values honesty, respect, and family-like service, I have to say—working with Manny Platero was an absolute pleasure. From the moment I arrived at Rick Hendrick Chevrolet of Buford, he treated me not just like a customer, but like family. Let me tell you, sometimes as a Latina, especially with a bit of an accent, you worry you won’t be taken seriously or that people will try to take advantage. But not with Manny. He listened to me carefully, explained everything clearly (even the things I didn’t understand about the car), and most importantly—he made me feel respected. What I appreciated most was his patience and the way he took the time to walk me through each service step. He wasn’t trying to push unnecessary work or confuse me with technical words. He was genuine, kind, and very professional. It reminded me of how we take care of people back home—with warmth, but also with integrity. Gracias, Manny, for making this Cuban woman feel seen, heard, and well taken care of. You’ve earned a customer for life—and I’ll be sending my whole family your way. Con cariño, María G.

Saw the Ad from Rick Hendrick in re a Porsche Cab for sale on Facebook. Good price, good looking car. Bought it and the experience was delightful. Hassen Beshir, my salesman, treated me like Royalty---going so far as to drive me to my bank for a check. I would easily give the dealership a 10 Star rating...but the limit is 5. Keep up that level of satisfaction and the Georgia folk will be beating on your door. Sincerely, Mike Eberlein

Great dealer for your custom order!
Worked with Ced Thatch in Sales on a truck order. Although I was unable to purchase due to my financial situation he was great to deal with through the whole process. The ordering process was quick and easy. Pricing was very good and my sales rep was very responsive throughout the wait anytime I had any questions. I would definitely recommend if you are looking to order a truck or SUV even from out of state. This is a big dealer with lots to choose from and a solid office team to help with your purchase.

I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!

Great Customer Service and Assistance
The salesman (Jerrel) was great to work with because he helped me while he was there Orr if he was off that day. He got me a car from another store then found out there were problems and found me a car around the same price range that was newer and less miles. Thanks for everything!
