Used Mercedes-Benz GLC 300 for sale near Old Greenwich, CT under $899,990

Best deals with no extra fees like everyone else. Thank you for your honesty and fast response. Definitely will be back for my next car purchase.

I have own 2 GLC 300 automobiles as 2017 and this 2019 sportier model AMG upgrades. These are the best cars I have ever owned. Comfort and looks are beautiful. I highly recommend this model.

My mom and I went to at least 4 dealers before coming to Showroom Auto, I was in the market for a Lexus IS350 F-sport and we found a beautiful vehicle at Showroom Auto but it wasn't the car that made us purchase here, it was the interaction. Chris was really relaxed with us and he made my mom feel truly comfortable. He's a true professional and extremely knowledgeable in his field. I definitely reccommend Showroom Auto.

Love the car. 4 cylinder turbo, it has enough oomph to get on the highway quickly, but very comfortable in day to day local commute. AWD excellent in snow. In E mode, engine stops when vehicle does; mileage is very reasonable. Given the grill, black exterior and cranberry-accented seats, it’s a head turner (“Mercedes on steroids” was one comment). Only complaints are have to duck head to get in- and I’m only 5’9”, and the trunk space in less in the coupe model (which also looks sleeker than the square back, so take your pick).

Our experience purchasing the BMW 328d was outstanding, thanks to Jeremy's responsiveness, helpfulness, and professionalism. From the moment we walked through the door, he was ready to show us exactly what we were looking for, along with other great options to consider.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

James made my car buying process super smooth and easy! And these guys have some really nice cars indoors I was impressed!! Thanks for my new Benz and super low rate

I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

Really impressed with this dealership, particularly the service department. I was driving two kids to college, got a flat tire coming across the Tappan Zee bridge, 20 minutes into a 9 hour trip, happened upon them, had my tire changed in under an hour and on my way again. Fast, professional and a terrific experience. I was so impressed, I may have them regularly service my car even though I live in CT.

This is our second GLC 300. We love the size and features for our needs (two people). Good mileage 27-29+ around town, 30-32 highway. Smooth ride, easy handling, and I think, nice styling. Newer models have larger screen and are more electronically controlled from the screen. Fields of Orange Park, Fl. has great Service, not cheap, "Mercedes" nuff said, but they will take care of you.

We just bought a CPO 2022 S580 Mercedes! Joe Horneman was our salesman, and he was an absolute joy to work with. There was no pressure, and he was very accommodating to our needs. We'd been looking around at multiple dealerships and no one treated us like family as Joe did. Throughout the entire process, Joe was patient, knowledgeable and available to us for questions and discussions. This is my 8th MB purchase, and I've found a new dealership to work with, and a new salesman!!

Best car I’ve ever owned , very comfortable and smooth ride , great on gas . Also as long you do the proper maintenance the car will last you , had for for 3 years no problems whatsoever. Also very spacious for size. So i definitely recommend this car to family friends or whoever looking for a nice car.

Leticia did an outstanding job helping us through the entire purchase process! She went the extra 10miles every time to address our questions and concerns with patience and a smile!

Owned for 2 months, replaced a 2023 Buick Envision Avenir. Much better car, more comfortable, more luxurious. Used to Drive Lincolns, stopped as they are now made in China. Compared to Jaguar and Cadillac, clearly better car.

Every one was well informed and helpful. My sales person was Matthew Boer. I felt very comfortable with him. Both due to his knowledge and attitude. A hugely different experience than I had elsewhere. He tried hard and succeeded in getting me the car I wanted. Joseph and Jonathan also deserve a mention. Thanks guys.

Excellent service. Great place. Great people. Fresh coffee and muffins, bagels etc. They take care of you like a family. Carlos is the best.

It’s been a great month of getting to know my new vehicle! I waited 12 weeks from the date of order to pick up my new 2023 GLC, and it was definitely worth the wait! I selected the Exclusive trim, Driver Assistance and AMG Line packages with several add-ons, and I could not be happier. My previous car was a fully loaded 2019 GLC 300, and it was unfortunately totaled in early February on a road trip. My first one was the favorite car I had ever owned and it kept us so safe during our accident, so I knew I wanted a second one. I did not realize I would have to wait so long to get a new one but I am happy I did not settle for anything else. The drive is sporty and smooth, and very quiet. It has a slight hesitation from a full stop. Once you take off it picks up very quickly and sport mode on the freeway is great. The upgraded electronics have been easy for me to understand after I read through the owners manual. One recommendation I have is to turn off the automatic speed change if you are using cruise control and happen to go through a construction zone. The cameras pick up the sign and slows the car down very quickly. I prefer to adjust to those situations manually. The car feels a bit bigger and is so attractive and comfortable. It feels much more luxurious than my 2019 did, and in my opinion the upgrades are worth the price. I absolutely love this car! Happy Shopping!

Kevin has been an incredible sales person. One of the best I’ve ever had will continue to business with them.

Marc took his time to explain everything to me. They have an amazing selection of luxury cars, and they are very professional here

I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

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!

Awesome Dealership! I had a pleasant experience at Mercedes Benz of White Plains. Ardit Shabi (Sale Representative) was very professional, friendly, polite and extremely knowledgeable. He listened to what I was looking for and helped me find the perfect car. Bob Binett, the CPO manager, was excellent as well. The help from both of of them, made it possible for me to get my dream car. You both made my car buying experience a memorable one. All of the other staff here were nice as well. I love the 2 beautiful key chains you gave me. Thank you for arranging registration for me. Last time with BMW, I have to do it myself. What a wonderful service! This is a great dealership that you can trust. Thank you so much.

I have owned glc300 AMG line for two years and I have positive things to say about it. Only critiques I have of this vehicle are the lack of more screens as there are still analogue speedometers on these year model. Interior could also be of higher quality materials. Rear is good

Mercedes of Massapequa makes shopping for a car easy and effortless. Albert helped me through the whole process of buying the car and getting the best deal possible. 100% recommend this dealership and make sure to ask for Albert!

HAVE. NOT PUT MANY MILES ON HER YET, BUT SO FAR LOVE IT! QUIET, FUN TO DRIVE, A GREAT INTERIOR, LOVE THE WAY ALL OF THE GAUGES AND THE GPS SCREEN ARE ARRANGED. STILL HAVE NOT LEARNED ALL THE CAR HAS TO OFFER, SO MANY BELLS AND WHISTLES!

TONY MANGIOLINO WAS TERRIFIC HE WAS A TRUE GENTLEMAN--NEGOTIATION PROCESS WAS PAINLESS. DID NOT PURCHASE CAR YET--BUT WILL TURN BACK TO HIM IN NEAR FUTURE FOR PURCHASE

I love this car. Quiet and just the right size . Super comfortable on long drives. This is my first SUV and I love the visibility as compared to my small Mercedes that I traded in for this. The upgrades and cameras are so improved also. The only thing that could be better is if it was driverless!!!

It’s probably one of the best luxury car dealership in New York if not in the country, and Victor Cosme our sales consultant made that possible .

This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

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.

I had an incredibly smooth and painless new car leasing experience yesterday with Trentino Manco and his colleagues at Rallye Motors in Roslyn. I was not surprised – I have purchased and leased my last four cars with Trent’s assistance. He is always professional, helpful, honest, and trustworthy. Trent has made the previously unpleasant car buying/leasing experience a thoroughly enjoyable one. I wholeheartedly and highly recommend contacting Trentino Manco and his team if you are looking for a new Mercedes. You will be in good hands.

MB of Rockville Center is the best dealership. Thomas Ahrens is the best sales agent, ask for Tommy if you are in the market for a Mercedes Benz. The staff is very friendly and professional, I enjoyed my purchasing experience.This was my second Mercedes Benz.

Best customer service and very smooth process. Highly recommend going to Albert Salib. He made the purchase smoothly. I recommend my family and friends to see Albert!!
