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!

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.

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.

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.

Second car this year at Pristine!
This is the second car I purchased from this dealer. In March, I purchased a 22' Outlander SEL for my company car. This week I went back and purchased another 22 Outlander SEL for my wife! Travis, our salesman, went above and beyond answering my questions and finding the perfect trim and color for our new car. I was pleasantly surprised at how courteous and professional Ryan was when it came down to locking in a good price and a monthly payment I was comfortable with. This dealer as a whole has been nothing but OUTSTANDING for me and my family. This is my 8th Mitsubishi purchase over a course of 20 years. I've been to my fair share of Mitsu dealers in the past and can honestly attest to their professionalism and outstanding service.

Excellent purchasing experience at MB of Hunt.
We were in the very capable hands of Anthony Mastroianni, who expertly guided us through the process of purchasing our car. Anthony was extremely professional, very knowledgeable, thorough, and of course patient. He was very attentive and made every effort to answer all our questions and concerns during this process. Additionally, touring the Huntington facility reassured us that we would be in good hands on all our subsequent service visits. We continue to be most pleased with our recent car purchase and would highly recommend our sales consultant, Anthony Mastroianni, to guide potential buyers through this exciting process. Thank you Anthony!

SLC FINAL EDITION
Peter Langlois is an honest, professional who knows how to help a customer find the car of their dreams. I have been a customer of MB Smithtown since 1988 and in all those years of great experiences I have met no equal to Peter Langlois in Sales. Thanks to Peter reaching out to me I was able to purchase the SLC Final Edition before it disappeared! Peter's assistance and follow ups are right on the money. A car is an important purchase for anyone, but if you love cars, then it's very important. If you love cars, then I would recommend that you request the very best there is: Mercedes-Benz of Smithtown and Peter Langlois. Start a relationship that will last a lifetime of worry-free driving: see Peter Langlois and your expectations will be exceeded in every way!
