The car buying process can be hassled and stressful, but
The car buying process can be hassled and stressful, but I had the most pleasant and happy experience dealing with the team at Bridgeport BMW. If you’re looking for a prioritized experience vs predatory experience, then it is worth giving Bridgeport BMW your time and your business. Big thanks to Zashley, Paul and Charles, I appreciate your time, patience and accessibility. WJ
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.

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, 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..

Alexander Sagredo-Teacher/ Adjunct Professor
When my daughter decided to attend college in upstate New York, my funds to purchase a car were somewhat limited. After visiting several dealerships, I eventually ended up at M &A Motors. The difference with Medi (owner of M& A) in comparison to all the other dealerships, is that he LISTENED carefully to my situation instead of just trying to push whatever car he had on his lot. The rest is history. To this day, M& A Motors is my first choice when I am in the market for a pre-owned vehicle.
Perfect for the family of 6 like me.😍😍😍
I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

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.
Very happy with my purchase from RBM Alpharetta.
Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

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!
Love this car
This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

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!
Great SUV
My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

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.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

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!
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Andrew P was our salesman and he was very friendly and knowledgeable. He wasn’t pushy at all and helped us get the best deal possible. Everyone we dealt with at Pristine was a pleasure to work with. I would recommend this dealership for your next car purchase.

I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.
