It Doesn't Get Any Better Than John Hart
his is my 5th Mercedes Benz car and my second car from Mercedes Benz Manhattan. I worked with John Hart, who in my mind, is an exemplary sales professional. John worked with me through all the different models I was interested in until we came up with the right car at the right price. Ultimately, we had one built. Last weekend I went to the dealership to pick up the car. Again, John did everything he could to make my experience as pleasant as possible. I drove home feeling happy knowing I had made the right choice. John Hart made the entire process as easy and seamless as possible. We also had a little fun along the way. John will be my go to salesman in the future. I hope he never leaves. If you're looking for a new Mercedes and want to work with a really nice and honest salesman, please give John a try. You won't be disappointed.
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.

Excellent customer service
They were very diligent in getting back to us. Unfortunately we could not agree on a reasonable price for our trade inn
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.

Happy with both our Mercedes purchases with Mary K
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

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

Best dealership I have been to
I’ve been to many dealerships during my car search, Fast Track has easily been the best experience even though I didn’t find the car for me: • Ramon is a genuinely good guy, big heart, no pressure • Best test drive experience ever (you’ll see what I mean) • cars super clean • every dealer adds on an addtion charge. Fast Track’s added rate was the lowest of the 8 dealerships I have been to • I was skeptical of the positive reviews. The look of the place isn’t impressive, but the way they run their business is an outlier compared to other dealerships I worked with
My Sixth Mercedes Benz-Fantastic Cars
The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

I’ve been shopping for cars all my life, but , for sure I have had the best experience at fast track motors. I just took delivery of my 2023 Mercedes S63 Amg, and I could not be happier, it was a seamless experience , and I left at ease with no buyers remorse. My experience with ceasar as a finance professional was top notch. Will recommend all my friends and family here. Rme

I recently bought my first car from Carz4us, and the experience was fantastic. The staff was incredibly helpful, guiding me through the entire process with patience and professionalism. The selection was great, and I found the perfect car within my budget. Highly recommend Carz4us for anyone looking for a hassle-free car buying experience!
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.

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.

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!
