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.

Buying a 2017 E300 for the right for price
It’s probably one of the best luxury car dealership in New York if not in the country, and Victor Cosme our sales consultant made that possible .
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.

Saw the g class bought the class in less than 3 hours. Alfonso the sales guy was a PRO! He did FaceTime walk around. I've been shopping for weeks and this dealership had it priced right. From NY to Texas. Will let you know about the shipping and final outcome and one last point NO hidden xx fees like doc destination or whatever. This is a first class Merc dealer.

I bought two cars from Mike Barrows.
I bought two cars from Mike Barrows. Mike's salesmanship goes unmatched. He did not pressure us at any point and was always willing to do his best on a price for us. The transaction was quick, easy and smooth. Just to top it all off Mike donates $50 dollars for every car he sells to united for the troops and having two grandparents that served this really blew me away. Thanks Big Mike!

Extremely Happy working with Mary Kodak with both our family cars purchases. Looking forward to purchasing a SUV with Mary as soon as the one we're looking for is available. First purchase was a 2016 E350 and the second was a 2017 S550. Mary made us feel cared for and was extremely efficient. Very happy with Mary

The entire dealership staff at CPM was incredibly welcoming, making the process smooth, efficient, and completely hassle-free. I got my Jeep Compass Latitude from them, and the experience exceeded my expectations. If you're looking for a top-tier car-buying experience, I highly recommend CPM and working with Jeremy - he made everything seamless and enjoyable.

this was the second time that I was in for what I consider major repairs. Initially, the service tech and I didn't hit it off very well. Then Tim the service manager stepped in and was great to deal with. The repairs were completed in good time and they did a fantastic job. I'm happy I chose this dealership.

Steven David Benzel Busch
I rarely write reviews and for the very few times I have done so in my life time, it was always to point out a bad service. HOWEVER. I had exceptional experience purchasing my E400 Coupe with Steven David from Benzel Busch. Since getting my first license back when I was 16, I bought and sold 10 different cars and Steven by far exceeded any of the sales person I have worked in the past. He was very responsive to all of my emails and phone calls. I almost got a reply back within 5 minutes from sending an email and we had many emails back and forth as I was purchasing a vehicle out of state. He was very detailed and truthful when describing a vehicle that I was purchasing. There were few times where he reached out to me first on items normally you wouldn't expect sales person to. Thank you, Hyunbin
