Used Mercedes-Benz GLS 450 4MATIC for sale near Old Greenwich, CT

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.

Quick response and knowledge in answering all my questions. Unfortunately, the vehicle I was interested in purchasing was sold.

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!

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.

I bought my first BMW in 2014. A new 640XI convertible... I have purchased many new vehicles including 5 Lexus 4LS models and 1 Sports coupe. The BMW was without a doubt the best. Now with regard to customer service as well as service departments (which is almost as important as the car model I select) Rallye BMW was without a doubt the best in both categories. So now that my BMW is eleven years old my wife and I decided it was time to look for a new car. There wasn't much to think about so we returned to my Rallye BMW dealership in Westbury and go for a test drive. Immediately after that test drive we returned to the dealer and negotiated the purchase of a new 2026 8XI convertible. We met with our service advisor, Frank Trotta, who has been taking great care of the 2014 model and gave him the good news: Frank we are buying a new BMW. Mr. Fitzgerald, When you and Mrs. Fitzgerald can come in I will introduce you to my friend Angelo a sales Representative...We met Angelo, another great representative from Rallye BMW and now we are waiting for delivery. I highly recommend If you are looking to buy a new or used BMW you give Rallye BMW, located in Westbury NY a visit.

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.

Marc provided me excellent service and I purchased an Infiniti Q 50S thank you so much Auto Expo you guys are amazing

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.

Excellent customer service. Silver Star Motors was extremely prompt in addressing the issue with my car during my recent service visit. I highly recommend Silver Star Motors.

Great experience buying the car I always wanted here! Victor Varga and his friendly and adept colleagues made the whole experience simple, pleasant, and thorough. And with their no-pressure help, I purchased a great car with the right maintenance plans to make it last. Highly recommend a visit to Goldens Bridge Mercedes Benz; these friendly and super-experienced professionals make car buying what it should be! 5 stars for sure!!

Leticia was great! She made everything easier with getting my car. Everyone I spoke to was incredibly nice and always were willing to help with any problem or question I had. Great dealership experience every time I showed up!

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++

Stanley was very professional and knowledgeable of all features my car has to offer.! I was offered the opportunity to schedule a same day appointment to have Stanley go over all the features.! Truly a great Penske agent.!

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..

After searching for over two weeks, I finally purchased a 2023 Toyota Camry as my first car—and C&K made the process smoother than I ever could have imagined! The team was knowledgeable, transparent, and answered all of my questions without any pressure. Best of all, there were no outrageous or hidden fees. I couldn’t be happier with my experience and would absolutely recommend C&K to anyone looking for a car!

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.

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

It has been a pleasure working alongside Carlos at stream auto. He and his team made it an easy smooth transition for me to leave there with a great car and a smile on my face thanks again team five stars to Carlos

Complete and professional attention to my purchase from order to delivery and after. The salesman I worked with, Servet, was a pleasure to work with.

Best experience and fastest total transaction I’ve had in my car buying experience. From the easy access to the dealership off the West Side Highway, to the amazing environment they’ve created inside, to sales consultant Gregory Gazzola’s expertise and ability to read a customer and deliver the vehicle I wanted, at the price I could afford, expeditiously, it was absolutely the best experience. I emailed Gregory this morning, he found me a vehicle, presented a deal, and gave me a pick up time for earlier this afternoon. I was in and out of the dealership in less than an hour today – I’ve spent more time in Home Depot buying a grill. I highly recommend Mercedes-Benz of Manhattan and Gregory.

Great experience. Ask for Pablo. Very personable. Received a great deal!. Thank you again Pablo

Buying at TSF Auto was a pleasurable experience. The cars were sweet and the prices were great. I would like to thank my salesperson, Egor (I'm not sure how to spell his name), for his guidance. He's one of the 'good-guys'.

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.

I just purchased a 2003 Mercedes SL 500 from Jordan. He was very honest and straightfoward and there was no haggling on price. I asked about having the vehicle inspected and they transported it a mercedes specialist shop. There were repairs that shop said needed and they paid to have the repairs done. No argument . I was very impressed with Jordan's professionalism and I would definitely do business with them in the future. Keep up the good work boys.

I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV
