Delightful & pleasant experience with Vincent and Ed at
Delightful & pleasant experience with Vincent and Ed at Mercedes of Fairfield. No other Mercedes dealership compares to this service organization.
I’ve had many Mercedes-Benz models over the years,
I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

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.

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!

PJ Uva made my entire car buying experience seamless. He is caring and down to earth. He put me at ease while taking the time to review all of the vehicles options. I also closed out the paperwork with Jessica Pugliese. Both Jessica and PJ were up front and transparent with the pricing and extra service options. I would definitely recommend this dealership.

Marc is the go to guy at Auto Expo he’s Sales and has years in the business. Real honest guy and their cars are amazing for the prices. It’s a luxury dealership!
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

I had an incredibly smooth and painless new car leasing
I had an incredibly smooth and painless new car leasing experience yesterday with Trentino Manco and his colleagues at Rallye Motors in Roslyn. I was not surprised – I have purchased and leased my last four cars with Trent’s assistance. He is always professional, helpful, honest, and trustworthy. Trent has made the previously unpleasant car buying/leasing experience a thoroughly enjoyable one. I wholeheartedly and highly recommend contacting Trentino Manco and his team if you are looking for a new Mercedes. You will be in good hands.

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.
