Nervous first time buyer
My mom wanted to purchase her first ever car, but was extremely anxious & nervous about the process. Greg made all her anxiety & nervousness disappear. He took his time & explained everything to her, sometimes numerous times until she was comfortable and understood everything. He is truly a credit to his chosen career & if I may say so, humanity. I would not hesitate recommending Greg to anyone who asked if I knew a trustworthy salesperson in the car dealership world.
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.

My recent car buying experience with Acura of Stamford
My recent car buying experience with Acura of Stamford stands as a paragon of excellence, unparalleled in the past three decades. My journey commenced with an exhaustive three-week exploration of the offerings from BMW, Porsche, and Land Rover. This odyssey involved navigating through their artificial intelligence bots, concierge services, client interaction layers, and ultimately, their sales departments. The process was akin to being a mere ticket at a deli counter, devoid of personal touch. Serendipitously, I discovered Acura of Stamford through CarGurus, where the dealership's commendable ratings caught my attention. Using their online booking system, I scheduled a test drive overnight and was promptly greeted by a text message from a human representative, confirming the car would be ready. Upon my arrival, Christina made instant introductions to Ty and Jaime, no bots insight. The entire team exuded genuine personality, devoid of any aggressive sales tactics. I am very happy with both the purchase and the trade-in price. This experience has solidified my intention to exclusively procure vehicles from Acura of Stamford henceforth. Should their current inventory not meet one's desires, I highly recommend contacting them to inquire about potential sourcing options.
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.

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.
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.

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.
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.

I worked with Jesse and Jimmy and they were excellent. Jimmy went above and beyond to ensure that I got the car of my dream and the best protection needed. I couldn’t be happier! I definitely recommend this dealership.

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 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.

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.
