Used 2021 Mercedes-Benz GLC 300 for sale near Harbor Isle, NY

We have been leasing our vehicles at Advantage Hyundai for several years. We recently leased a new Tucson. Our sales advisor, Opal, was very helpful. Their service department is excellent. We highly recommend them. Carol & Jim

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.

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 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.

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!

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.

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. ….

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.

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!

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

We’ve been buying cars here for the last 6 years. My go to place to purchase all my cars. Everyone is friendly.

It was great I didn't feel pressure by the sales person Can you inform me of a lot of things I didn't know made me Trust the information he was giving me

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!

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.

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

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

Great experience dealing with Rafael got what I wanted definitely will be back in the future

Great car. In fact, I would treat it like a new gadget. Using the autopilot is a real thrill.

I highly commend Mr. David Garcia for his knowledgeable, professionalism and caring follow-up manner in which he demonstrated, during the purchase of my Mercedes Benz. Although I was disappointed in dealing with the sales/financial manager for his inappropriate, condescending attitude, Mr Garcia was able to diffuse our differences and finalize the purchase.

Ryan Lewis was a very considerate and professional sales person. The financial department Was very polite and professional as well. The dealership is always very clean and welcoming. I would recommend people to the Riverside dealership. Thank you.

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