Pay attention what get in your hands paperwork throughly
Pay attention what get in your hands paperwork throughly read it carefully and see everything they put in it such extra extra cash that you didn’t say and extra money makes it go up higher that you can’t afford the extra payment.Now you see how much gap insurance $$$ added in the paperwork and makes sure you get a lawyer go with you when getting used filthy car full of dog hairs.Makes sure you have mechanic on hand too.They will sell you a car without license which is illegal.Don’t use no co-signer.Don’t use Ally financing on new or used vehicles.Even if you pay it off tell you getting gap refunds on mailing letter.they will keep it cause you don’t qualify for it.Keep up with all your paperwork in a file and payment history on papers like print out.Get your payment down as low as you can and 84 months is long ways to go.Do research how to save money on used or newer car without all that crazy extra add on.They’re trying make money of of you even on the elderly people.Have a great day everyone

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!!!!!

The service manager was great.
The service manager was great. When I had questions about the results of my cars inspection they went into detail on how they perform the tests and come to the conclusions of the problems with my car. It didnt feel like I was being talked down to because I am not a car expert? instead they worked through their responses with sincerity and professionalism.

I found my car on the internet and scheduled a test drive
I found my car on the internet and scheduled a test drive with Kiara. I was her first potential customer. She did a great job even though I might have scared her on the test drive. I ended up coming back after I sold my truck and was able to work a fair deal after some good negotiations. Part of my negotiation was to bring my car back and have a few things fixed on the car that I wasn’t happy about. After about a week, I was able to bring my car back down to drop off for a few days while the work was being done. I worked with their finance guy Keon. He lined me up a loaner to drive while they had my car. After about three days, the work was done and I went to pick my car up. I was very pleased with the outcome and they even fixed a few other things that we didn’t agree on but new I had questions about. They listened to me as a buyer and were willing to work with me. If you want to avoid big dealerships, they have a great inventory up nicer cars and are great to work with. I will shop with them again!

Highly Professional and Honest Staff The team at Cobb
Highly Professional and Honest Staff The team at Cobb Luxury Cars was extremely professional and honest. They helped me purchase a beautiful Lexus ES350 with a reasonable down payment. I also got a 4-year extended warranty through them, and when I needed to file a claim, all the repairs were fully covered with $0 out of pocket. Big thanks to the Cobb Luxury Cars team for making the entire experience smooth and stress-free!

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.
