Used Mercedes-Benz GLS 450 SUVs for sale near Fountain Hills, AZ

Jozsef Horvath made my experience a great one. His product knowledge vs competition convinced me that I was making the right choice. Jozsef’s no pressure approach was a breath of fresh air, and his communications with me during and after the sale have been fantastic

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.

We had an excellent experience at Mercedes Benz of North Scottsdale. The process was very low-key and smooth. Our sales team, concierge service and parts department were all very attentive to what we were asking.

Perfect, Professional, and Pleasant Total Customer Experience with Jeff Maddox when I bought my car. Everyone knows buying a car, especially at a dealer can be, and is often reported to be a miserable experience, or at best annoying, and a time suck. Go see Jeff Maddox. From test drive to answered questions to sale… you will want to go back and do it again. Trust me.

This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

TUAN PHAM is attentive and accommodating. We drove down from Prescott and the car was ready to test drive when we arrived for our appointment. The process of purchasing was seamless and the Finance department had a clear understanding of our financing options.

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.

My service clerk D did a great great job, there were some issues and she went over and beyond to resolve the issues. This company should pay her more. This young lady is not like alot of young people, she gets the job done. They should give a promotion. Thank you D once again. David Eustice

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.

Glenn Davis was great help in making my purchase. He was very professional and got me in and out of the dealership. This was the best experience I had purchasing a car. I purchased a used Acura/MDX. They offer competitive pricing and great service. I highly recommend Glenn if you are in search of a car. He will give you a great experience and prices. Thank you Glenn, I hope to continue doing business in the future with you.

Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

This is my 3rd new car from Coulter, that in itself says volumes. Allen was great as always, our 2018 Terrain is wonderful and sits nicely next to the Acadia Limited I bought the last time. I highly recommend Coulter to anyone wanting to purchase their next vehicle.

I had an outstanding car buying experience. Matt was so kind and helpful, he made sure that he had a full understanding on what I was looking for in a car. 10 out of 10 would recommend!!!

We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Was looking for a quality used vehicle and Andrew Chaidez was able to find exactly what I was looking for at the price I needed. Andrew went above and beyond to make the deal happen for me and even was able to get a much appreciated second key for the vehicle. I would recommend Andrew and this dealership for anyone looking for a quality vehicle and good customer service.

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.

I'm limited to just 5-Stars! Our family had an exceptional experience at GMC Liberty all due to the service and expertise of Anthony Sanders. We were looking for the coveted 2025 Yukon Denali AT4 (hot ticket item). He knew our needs and was an open, honest, and most importantly a non invasive salesman. This has been our best automotive purchase experience and we couldn't recommend anyone more highly.
