Thank you Anthony, Ray, Romina, Cassandra, and the staff at Stream Auto Outlet Amity! Thank you for treating me very well, and helping me get a great deal on my 2008 Jeep Grand Cherokee Laredo. I highly recommend Stream Auto Outlet Amity when looking for a used car.
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.

I recently purchased a car from C-Rich, and the service
I recently purchased a car from C-Rich, and the service was exceptional. When I booked my appointment, they told me to be prepared to drive off with my dream vehicle, and they made it happen. The dealer was professional, knowledgeable, and made the entire process smooth and enjoyable. Educators, go get your dream car from C-Rich – you won’t be disappointed!

Used car
Was able to get my luxury used car with no hassles all questions answered. Would buy future cars there and refer friends/family. Melissa was a great help.
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.

Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

Ray Davino is best person at to work with
Ray Davino always is the best ! He recommends warrantees for future use and has great suggestions for the maintenance of my car. I have been with the Smithtown Mercedes dealership for over 10 years and highly recommend everyone here.
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..

I can not say enough about this wonderful dealersh
I can not say enough about this wonderful dealership, I have been a Mercedes Benz owner for 25 years! Mercedes-Benz of Huntington has really kept their promise to make all their customers happy. I especially want to say That Steve Varus in sales and Randy in service has made it easy to purchase and accommodating with the service . This is what makes a repeat owner of 25 years , happy to drive such a wonderful vehicle.
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.

I bought this vehicle is a retirement car.
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.

Tom Aveni is a pleasure to work with
Tom Aveni is a pleasure to work with. We live in northern VA. He was so responsive to our needs that I took the Acela train and Long Island Rail to get to Huntington, NY and bought a GLC300 from him. Great experience all around. And even after a couple of months he still reaches out to make sure everything is good. He also ordered a part that was hard to find and kept me informed until it was found and shipped. He cares and he follows through.He is now my go to advisor for all our Mercedes needs.

I recently purchased a 2020 Audi Q8 from Turn Auto Mall, and I couldn't be more pleased with my experience! I got an amazing price and a great APR rate. Jesus, Arthur, and Elysha were fantastic to work with—professional, friendly, and knowledgeable. They made the entire process smooth and easy. I highly recommend this dealership to anyone looking for a great deal and top-notch service!
Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Great service with David
I had a great experience with my time at Masters. I was assisted by David and I must say he was a excellent salesman. He was very patient and understanding of my needs while shopping for a new vehicle. He’s prompt with his responses and is always available to answer any questions. Highly recommend him to anybody inquiring to buy a new car. Great thorough guy all the way around.

THE BEST IN THE INDUSTRY
Fortunately for me I had the best experience with Mercdes of Smithtown. I own a seamless Gutters company and have purchased 4 Diesal mercedez trucks since 2020. Joe my sales men went above and beyond. The dealership treated me so fairly. We did business by phone and I could not say better things about this location. In fact I will be calling them to buy another truck soon. Keep up the great work, and awesome Customer service.
