Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

Mo was great she helped me and explained everything. She is great thanks mo I love my new car!

Bought a Chevy Traiblazer with Fabio this week and I had a great experience. Everything was smooth and easy

Greeted well and by name. Service department found my unused voucher for service and I payed zero to be treated very well. Happy and friendly and knowledgeable folks spent their time helping ME. Mechanic?s video extremely helpful.

I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

Easy to work with and very accommodating. Very professional and helpful. Shootout to Rick and Rob

My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

Thank you very much for Greorge Adam who help me with my car .George is very profesional and very helpful .Great job!!!

From the moment I stepped onto the lot at Florida Fine Cars, I knew I was in the right place. In an era where genuine customer service feels rare, this team reminded me what true professionalism and hospitality look like. Every interaction—whether with the front staff, the sales team, or management—was warm, patient, and sincerely focused on making my experience exceptional. But I have to give a special thank you to Ralph, who is truly one of a kind. His knowledge, honesty, and ability to connect with customers is unmatched. Ralph doesn’t just sell cars—he builds trust. He made the entire process smooth, transparent, and enjoyable, and he treated me and my family with a level of respect and friendliness that left a lasting impression. People like him are the reason this dealership stands out in Florida. The prices were unbeatable, the inventory was impressive, and the service was nothing short of extraordinary. Florida Fine Cars has earned my loyalty—my family and I will be buying our vehicles from them from now on. If you’re looking for a dealership that actually cares about you, listens to you, and goes above and beyond to earn your business, look no further. Florida Fine Cars knows what true customer service is. Thank you again to Ralph and his entire team for delivering a world-class experience. Highly recommended!

I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

Anthony was terrific, he found a nail in my tire just by walking around car! He is so available and terrific knowing my needs. The facility was clean and very pleasant with confortable seats.

Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

I have test drive the range rover the X7 and I find this is the best for me , it has the room and comfort plus all the safety plenty of power too with a good mileage for a car this size .

My oil change was less expensive than my estimate that I received when I arrived. Nick, my service advisor, did a great job and got me back on the road in less time than expected.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

The whole car buying experience from start to finish was exceptional. Because I had worked with Sue before, I was grateful that she had time to help me find the right car this go around. Sue and the rest of the staff are all impressive professionals that serve their customer's needs. I've been driving the vehicle for a few months now. It's a big relief to be driving a reliable vehicle, especially since it's my dream car. It's definitely car love. I couldn't be happier.

Clean, professional, and very accomodating facility. Cynthia was courteous and explained the whole process in detail. I was very pleased with the service and the amount of time it took.

Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

Troy Mayer, thank you for taking the time to speak with me. While the car I wanted was already sold, I appreciate you keeping my information and keeping your eyes out for anything in my price range

Our family is thrilled with our new car! This dealership has an amazing team, super friendly and very knowledgeable. It was a pleasure working with everyone there! If you’re looking for a car, definitely check them out. I highly recommend this dealership!

I’m happy today to learn technology and all features, which Tucson 2025 offers, with Brand Ambassador Jenny Bethell. She is professional, kind and very patient with senior driver. Now I feel confident ,up to date with technology and safety. Thank you very much!

I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

Hands down the smoothest, friendliest car buying experience I've ever had. Sean was awesome and so was the finance manager who stayed late to finish the paperwork.

Great Experience! Everyone was very nice and helpful from the beginning. The process was smooth, easy and most of all I got what I wanted! Let the team know I am a very satisfied customer!

This is my second interaction with this dealership and I work with the same guy every time. Freddy, he is absolutely amazing. Above and beyond not once but twice. Delivered my new purchase to me an hour away. Always a pleasant atmosphere, the service department guy’s are awesome too!

All MotorWorld personnel, especially Ken Hoats in Sales, and Laura Muzzy, Business Mgr, were very knowledgeable, cooperative, helpful, and spontaneous to reply to all of my questions during the whole process of purchasing my new Lexus LC500.

EXCEPTIONAL Customer service!! I explained my concerns, they understood what I was saying and fixed everything! even what I had not mentioned. AND they only had I car for 1 day! Previously took to another dealer who had my car for 5 days and did what?? not sure cause still had issues when I drove off their lot. I will be back even if I have to drive 20 miles their level of great service is worth it! I have recommended Orange Buick to friends.
