New and used 2025 Mercedes-Benz C-Class C 300 4MATIC for sale near Haddam, CT

Had recent maintenance and repair done. Excellent service provided as usual. I recommend North Haven to anyone looking for mercedes service, you won't be disappointed.

Whole experience was outstanding. Don is an outstanding salesman and I will be contacting him in my next search for a vehicle.

I arrived to be greeted with friendly staff members. My salesman Kamran was great to work with and we were able to work together and get me into a vehicle I am very happy with.

Very good service. I was very pleased. The representative wrote an extended report of the service that was done. I would recommend them if you need service.

NLON Carriage House has the best customer service. I am always amazed at the personal response and care that I receive. I enjoy the waiting room which is clean and relaxing or the option to.have a car.

Can't say enough about our experience with the service department. We have a Sprinter van converted to a dog and cat grooming salon on wheels. When we are down we can't work. The service department always finds a way to get us up and moving again in the fastest possible time. Although we live only 20 mins from another dealer we choose to drive the hour plus it takes just to bring our van to the most honest, hard working dealership we have had the experience of working with. Thank you!!! Wagz and Wigglez

I brought my recently purchased car to the service center for a safety inspection. They found one issue and fixed it promptly. Overall service and communication were excellent. I will return in the future.

I normally don't buy used cars from dealerships because of the cost vs buying from private seller, but they happened to have a rare car that I wanted. I sent an email after hours and Mark Carofano responded promptly the next morning. They were very reasonable in the negotiation process and never tried to gouge me at any point. They even took care of a few maintenance items before handing me the car! Mark was extremely responsive and professional. When I got there he had everything ready and gave me some Mercedes swag. At no point did I feel like I was being pressured at a typical dealership. It was a very warm and relaxing atmosphere. They had ordered pizza for the staff that day and he offered me a slice. He made it feel like it was a family business! I flew to pick up my car and had a 7 hour drive and they made it totally worth the travel. Katie the finance manager was also extremely pleasant and easy to talk to! She made the paperwork process seem, well seemless! Sometimes you see 150 reviews at all 5 stars and you think well this is probably fake but the you experience it for yourself and understand how they got these ratings. This is the first and probably last review I'll ever leave for a dealership and I'm glad it was for Mark, Katie and Mercedes of New London.
