2021 GLC300 4matic
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.

Great dealer with some of the best selection of vehicles
Great dealer with some of the best selection of vehicles kept indoors I’ve come across. The staff is all very friendly and helpful and they helped me get the exact car that I wanted all in the same day!
Exceptional Comfort
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 just purchased a car from this dealership, and the experience was night and day compared to our prior one at another Mercedes dealer. The team here is incredibly friendly, down-to-earth, and easygoing—such a refreshing change! Albert is the one who helped us, and he truly went above and beyond. He was patient, helpful, and never pushy. He even took the extra steps to help us clean out our old car, remove the old box and items, and made sure everything was taken care of. It was such a smooth and relaxed experience—nothing like the stressful process we had at the other dealership. Highly recommend working with Albert if you’re looking for a great car-buying experience!

Great Experience!
I had reached out to several car dealers regarding Mercedes and BMWs and Rodni was the first to respond. Even though I live in Central NJ, his prompt response was impressive so I went out to this dealership a few days later. I wound up purchasing a beautiful Mercedes and I'm very pleased with my dealership experience.
