Used Mercedes-Benz GLS 450 for sale near Cos Cob, CT

I had a very good experience at Silverstar Motors. Their service department was courteous and very professional. They managed my problems quickly and efficiently. Joseph

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.

Giovanni is one of the best salesman that I have ever met he does a great job ..I bought about four cars off of Him he does great service. And gets the deal done. ….

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!

Matt and the used dealership was great. We talked via the phone and had everything prep and ready to go. The warranty guy, not so much. He was very pushy on a extended warranty after being told no 3-4 times. The only reason I deducted a star. We picked up a RX350 and was great process.

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.

Saw the g class bought the class in less than 3 hours. Alfonso the sales guy was a PRO! He did FaceTime walk around. I've been shopping for weeks and this dealership had it priced right. From NY to Texas. Will let you know about the shipping and final outcome and one last point NO hidden xx fees like doc destination or whatever. This is a first class Merc dealer.

Mr ANTHONY ANGELO was the best customer service we have experienced in quite a while. REPRESENTATIVES of this nature should be commended and placed in charge of that department .EXCELLENT CUSTOMER SERVICE!

Look at that smile !! Thank You Jerry Sherry for Maureen's 2024 GLC300 ! Amazing customer experience. Ralley Motors are the absolutely best in the industry. We will definitely be back for the next purchase.

We always have a great experience at this dealership! Bobby has consistently taken amazing care of us over the years, and we couldn’t be more grateful. Sally Morshed and Seth have also been exceptional throughout every step of the process—professional, attentive, and genuinely helpful. What really sets this group apart is their honesty and integrity. They’re not just trying to sell us something—they truly care about doing what’s right, even in today’s world where costs are rising everywhere. We sincerely appreciate the time, effort, and genuine care they put into every visit. A fantastic team all around!

I really like Nick Marin, my service advisor. I feel he suggests the maintenance and repairs I really need.

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

I purchased an X3 from Marc the service was amazing thank you so much Auto Expo!!

The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Very professional and experienced guys.. Victor and Igor made everything easy.. like 1, 2, 3..When we got a deal, I got out in 20 min.. payment, credit approval and keys from the car, excellent service. Thank you guys. I will definitely come again for my next car.

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 was looking for a nice convertible to use mostly during the summer and found a pretty good one here in Saddle Brook. Paid cash for it. Simple transaction. Robert my salesperson took good care of me.

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.

Fantastic people from sales Dominic Babbo, Darren for great service,and Sue for appointments.great dealer ship.

Extremely Happy working with Mary Kodak with both our family cars purchases. Looking forward to purchasing a SUV with Mary as soon as the one we're looking for is available. First purchase was a 2016 E350 and the second was a 2017 S550. Mary made us feel cared for and was extremely efficient. Very happy with Mary

I had such a great experience, everything was so smooth and easy, thank you Jim

Purchased a used car from Curran and the experience was a significant improvement from my recent past experiences with dealerships. Chris, Barbara, and Darius were all professional and a pleasure to work with. Truly no nonsense -- it was the easiest car purchase I have ever made. Traveled a significant distance to buy from Curran and would do so again.

If you are looking for honest sellers - this is the place for you. The managers are patient and polite, they explain everything without stress. Professional approach and attentive attitude. Thank you to the employees for the quality service. I have a pleasant impression of the salon.

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.

There was a misunderstanding in regards to the online pricing, but Jeremy reached out to me and we straightened it out. Upon making the deal over the phone and text, I was able to signed remotely, and pick it up on a Sunday. The vehicle was immaculate and I now wonder why it took me so long to upgrade my vehicle. I even left something in my trade in, which they are said they are mailing back to me. Thank you Jeremy for being so attentive. His customer service is top notch. Danzel and Hector made sure I got out of there as quickly as possible. Thank you team Stream Auto Outlet.

I have nothing but the best to say about my first experience at McMahon Ford. Sales, financing and the owners were all available and respectful. It was the best car buying experience I have ever had.

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.

Received a call 5 minutes after entering the Car I was interested in. Salesperson very friendly and knowledgeable. Still thinking about the car. They are at the top of my list.

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 .

The absolute best dealer I’ve been to by far in my search ! Low prices clean cars and low interest rate!!! Will refer my cousin to you as he’s looking to buy next week! Thanks Euro A++
