Used Mercedes-Benz GLC 300 for sale near Belmont, MA

I have been servicing my cars with Smith for over 35 years. Always attentive to my needs. Simply the best for Sales, Parts and Service.

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.

Great purchase of my new Lexus at Watertown location. Got my car in one day. Alec was awesome as he made the negotiation and transaction smooth. Highly recommend this dealership and Alec. You won't go wrong.

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!

Most of my dealings were with Chan. He kept me updated throughout the process without putting any pressure on me to buy or not to buy. I finally did purchase a2020 Fiat 124 spider Abarth. The car is everything Chan said it was. Couldn’t be more pleased.

nice car and no to expensive, comfortable, I can't explain how I like my new Mercedes Benz GLC 300 . My last car was very good , ut my new OMG......

I highly recommend this dealership for both sales and service…Brian in the service department has always gone the extra mile to help me keep my cars In good running order… I have been with this dealership for over 15 years both buying and servicing my cars with them…I trust them …

I have worked with Brian for quite a while and I have been exceptionally pleased with the service that he has given me. I feel very comfortable having Brian in charge with the service department because he stays on top of what has to be done. I have found that Brian is very caring, professional, and knowledgeable and when I leave the dealership I know that everything was done perfectly. Janet Edsall Fields

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.

Brought my 2016 E Class Wagon for routine service on May 6, 2025. The mechanic found some safety matters that my vehicle definitely needed and I was unaware of. My service advisor Stephen Lopes coordinated the service with the safety work. Steve set things up to get the additional work done and not to inconvenience me by supplying a vehicle to use. Highly recommend Mercedes-Benz Flagship Motorcars.

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

My advisor John is just coolest person very customer friendly and he goes above and beyond to help his clients and he keeps you updated on your progress

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 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.

This is my 4th new car and I would absolutely buy from IRA again. They made it the easiest buying experience never had and met me on every request I asked for even after taking 4k off the top.

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.

I got a great deal here, and it is clear that they only sell cars of great quality!

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.

Great service very friendly and professional. No stress with test driving or even "talking numbers" it was a great experience and will go back there again.

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.

Ryan is fabulous as the service leader. He exceeded expectations for professionalism, responsiveness, and courtesy. This is the second time I?ve had Ryan as my service person and he is just great. Well done.

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!

Had my GLC300 in for annual service, false warning lite, steering switch module replacement, tire rotation & balance, state inspection sticker. Steve, my service manager, provided a quality loaner and communicated with me during the few days the car was in the shop. He was professional, courteous and a pleasure to deal with.

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!!!

Excellent, understanding, professional and very efficient! Great company to do business with! Will definitely go back to buy future vehicles and highly recommend them to all my family and friends! Thank you Jaime and Tim!!
