Used Mercedes-Benz GLS 450 for sale near Fontana, CA

Even though my Gladiator was in the shop for nearly 8 weeks due to a parts shortage, I had a very positive experience in dealing with the service department. Michele is a top notch service advisor, who genuinely cares about her customers, and is quick to return calls. Thank you Michele, you have a return customer in me.

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.

Well, our experience with Tony was Fantastic! We found a car on the internet that we wanted and proceeded to go out there to purchase. Upon our arrival, Tony greeted us without delay and processed our request. We were out of the dealership within 1.5 hours, now that's a record! He got us our approval in a timely manner and it was all good!!! I would definitely work with them again. Now about the markup, it seems all the dealerships mark up and in order to stay in business so I don't worry too much. Plus the fact the car we purchased was in pristine condition with low miles it was worth the markup and the drive. I am a satisified!

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!

Great service very kind and professional. They were able to help me with a complicated situation.

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.

Although the car we wanted didnt work out, the customer service was excellent. MARCUS is a STAR! He should be in management. I have brought many mercedes in the past. Carmax is turning the tide when it comes to purchasing vehicles. The best thing to do when you buy any car is to take it to another mechanic, and then bring it back to the place to be fixed within the warranty period. The Truck I purchased from them a year ago had a few issues but they did take care of it and I've not have any problems since. Carmax has set the bar high for purchasing returning and anything to do with cars. BRAVO!

We managed to come to an agreement and purchased the car we wanted. There was not much negotiation, but the car was well priced to begin with. We agreed to pay $500 additional in order to drive the car away and have our mechanic inspect it. We got a week to report any issues and could return the car for a full refund if not satisfied by any necessary repairs. Ultimately the car checked out and the only problem was a piece of windshield trim that flew off on the way home. We negotiated a $200 refund and got the repair done by our mechanic so we didn’t have to drive the car back to the dealer. So far, so good.

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.

Great service and smooth transaction all the way. Very happy with my car and our sales person. The Used Car Manager was awesome and very kind. We Weill sure be back

Hassle free experience when I went into get an oil change with the help of Branden. Upon completion of service, I received an easy to read report outlining the results of inspection. Service department was very professional and helpful.

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

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.

Todd and his team were outstanding. They found just the right car for some friends of mine who asked me to shop for them. Customer service was exceptional. Pricing was very competitive, and the overall experience was a 10+. I highly recommend that you give these professionals a shot. You will be pleased.

We recently acquired a 2025 MB 450 GLEe from Walter’s with the help of Christian Aparicio. We our longtime MB owners so it’s a high bar with us but Christian exceeded all expectations. We couldn’t be happier and will certainly contact him the next time we need a MB. Thank you Christian!

Salesman Trey made the process easy and fast. I gave him the criteria I was looking for and he delivered even with my not so great credit. No hassle and no xx that I have gotten at other dealers.

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

Amazing service! Caring and attentive to my auto requests. Chris was a tremendous help. He was so patient and kind. Go get a car from STG! I have nothing but good things to say about my experience

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.

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.

Every one who we talk to in the buying process was great ! Definitely will be back soon Thank you

Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

On November 25th I went to the Mercedes on Ontario, and was looking to buy an electric car around 7pm in the evening, I was looking at the EQB 350 when this very nice sales representative Abel Vargas helped us and was very nice and interactive explained to us what was good about the electric vehicles, at the end of the point of buying the EQB 350 the transaction at around 2am Black Friday after hours but I will like to mention excellent and outstanding sales person human being his name is fadi batarni I had a situation where I had to call him, a couple days after but was out of town but still answered right away, like always nice friendly and helpful manner, and I really appreciate the help and appreciate the huge help on purchasing my EQB 350 Thank you much guys I really like my car.

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..
