Used Mercedes-Benz GLC 300 SUVs for sale near Southport, CT

I submitted an internet inquiry overnight, and as soon as they opened, Ephraim Senteio promptly reached out to me. I was very upfront about my busy schedule running multiple businesses and mentioned that I didn’t have time for window shopping. Ephraim completely respected that and connected me with Client Advisor Sam Al-Hajjaj, who was absolutely phenomenal. Sam worked efficiently to provide great pricing and handled my trade-in with care, making the entire process seamless. Jake DeMattia from the Genius Center was incredibly helpful, ensuring I had all the information I needed about my new car. Danny Rodriguez in finance was both friendly and efficient, making the final steps of the purchase smooth and stress-free. I purchased an X5, and I couldn’t be happier. 5 stars! My only feedback, as someone who frequently purchases high-end vehicles (Range Rover, Aston Martin, Acura, etc.), is that the dealership can get very busy and you can tell the staff was overwhelm, I think some technology could help them because people would get lost in the waiting room like we did :). This is understandable, especially on a weekend and the last day of the month—partly my timing. Overall, I look forward to building a long-term relationship with this amazing team. After almost 10 years, I’m thrilled to have a BMW back in my garage. Highly recommended!

I am a senior citizen and I want to feel secure while driving, and the SUV gives me that. I am on the short side so getting in and out was a new experience for me, but I learned how to manage it. Once, I found the seat setting the visibility is exceptionally good. It handles nicely on the road with quick pick-up, and the gas mileage is about average.

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

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.

Excellent Service as always Victor Baez was awesome and professional, he explained everything that needed to be done . Stoler definitely has very good employees. Thank you

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.

I bought a car from this dealer (land Rover), everything went well , the staff were friendly and helpful. Special thanks to antoine wilson , he was very professional , helpful and kind. Thank you

I traded mine in after 19000 miles for one reason, the run flat tires. they are $300 a piece and last 15000 miles. They might be an option, if you don’t mind putting new and expensive tires on every year but they don’t perform in snow after 5000. They don’t perform great when new to be honest, just better in snow with more tread. I loved the car, but living in hilly, snowy Pennsylvania, it just wasn’t practical. Think twice if you drive in snow or rough roads or just don’t feel like getting new expensive tires every year

Vehicle was sold before I was able to speak to a sales person. No problem! They were working on it before I inquired about it.

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

I've bought 4 vehicles from this dealership as a return customer die the the (CPR) - Courtesy - Respect - Professionalism I live in Delaware and make the journey for these three requirements for me to purchase. Ask for Lou 😉

Shout out to Genesis for helping us get our dream car , she was very honest , helpful , charismatic ! Anyone will like to buy a Car from her , and she did every single think to make sure my car was clean and in good condition . Also I love my car very comfortable.

Very good car buying experience; no high pressure with competitive pricing. Anthony the salesperson was courteous and responsive to all our questions.

Couldn’t be happier with my X4. Great deal at Infiniti of Greenwich !!! Super clean low mileage bimmer, 8k less than the BMW dealership

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.

We just leased a Sorrento from the White Plains dealership. We worked with Oscar and he was so nice, helpful and patient. He also remembered a week later when we came back to pick up the car that we liked the little song that comes on when you turn off the car, and he made sure to show us how to turn that on! Everyone that we interacted wit there was so nice!

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.

Leased a 2025 XC 60...Worked with Ryan Zucker. Outstanding experience...Client focused, knowledgeable and personable. I will be a repeat customer!

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!

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

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.

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.!

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!

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!!!

Mayorie and Raoul were outstanding , very professional and made the purchase experience flawless. I would highly recommend and will be buying additional vehicles from this dealership.

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.

Bought a 2015 Dodge Challenger with 5800 miles - great price compared with what the same car is going for today with 40K / 50K more miles. Process was easy. All my friends love the cards and strangers give me compliments. My only complaint was these cars go through an inspection where all problems are fixed. I bought the car in February and by the Summer when I finally turned on the A/C, it did not work. When I went to the repaair shop I was told it would cost me 41000.00 dollars as the hose was broken dehind the instrument panel. In my opinion this should have been caught by CARMAX and fixed before I picked up the car. Otherwise very happy - no problems other than that to date. CARMAX - please fix my A/C??????

A prefect car. So luxurious! Very spacious, great size for family and friends. Very reliable. Would recommend to anyone looking for safety and style at the same time.

The Acura team is thorough and I've never had a problem after any service. I'm glad the car wash machine was up and running as that and a vacuuming is a nice perk!

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.

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

The service was excellent! The workers really worked with my situation to make sure I went home with exactly what I was looking for. Would recommend 10 out of 10!

I'm not new to the Mercedes brand, as this is my 4th. This is, however, my first try at the Mercedes SUV. So far, I'm extremely happy. Favorite feature has to be the camel leather seats...an impressive update from the MB-Tex.

Great customer service Paul and Rich get you the car you want guaranteed and good condition

This car met all my needs. Very reliable and comfortable car. It has excellent quality and interior design. I drive my kids around the town safely.
