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

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.

Top salesman with a reputable dealership !
I have been purchasing MB automobiles from RVC MB since the 80’s .. I’ve always used the same salesman , Mr Tom Ahrens . Tom has always ensured that my new car purchase goes as smooth as possible .. I’ve always shopped price prior to making the deal - Tom has always beaten the competition prices - a great car coupled with a smooth transaction and a caring salesman working for a reputable dealership works for me !!
Great car!
Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

Luis, my sales rep, was helpful and professional!
I recently had a great shopping experience at European Masters with a salesperson Luis. He was very courteous and professional, obviously having customer`s best interest in mind. I initially contacted them over the phone and spoke to melissa, an internet sales rep. She politely answered all my questions and made an appointment for the following Monday. Upon arrival a vehicle of my interest was all prepped and shining. All in all I did spend there quite some time including a test drive, applying for financing, which turned out to be of better terms than my own that I previously was approved for and signing a contract. At the end of the day I drove off in my new car and was very satisfied with the process. Being a 3yr old the car had a highway mileage in Pennsylvania and drove and felt like new. Before this place I shopped in two other dealerships in Long Island and they both felt very disorganised and unprofessional. This place has a great selection of premium higher-end European cars, mostly BMW, Benz, Porsche. The condition of each looked top notch. And best part was that they walk their talk by following their promise and reconditioning some worn off part that didn`t look the best. Thank you, guys, thank you, Luis.

A great place to shop for any car
I have to say, this is my 4th stop within 3 days before I pull the trigger on the 2020 BMW X5 at Import Masters. I was surprised how I was treated considering I was way underdressed for the occasion. Most sales people would think WHAT THE xxxx IS HE DOING HERE LOOKING AT BMW X5. Edwin was very nice and made sure I was taken care of properly. All the staff are very friendly, even the little guys who are cleaning and waxing cars. They gave me all the information I need it on how to take care of the car. I highly recommend the place and make sure you don’t forget to check out and cruise around the neighborhood. You won’t regret it. xxxx a lot better than some other places I have been to. I advise you to make an appointment before coming in so they can bring it to the showroom. They have so many cars that almost stack on top of each other.

They sold me a 2024 Honda Accord.
They sold me a 2024 Honda Accord. Window sticker brand new was $36,000. After their fees (Which they did have guys) taxes, dmv and state fees.. we ended up paying $33,000. $3K more than originally listed price. This is still a fair deal. The vehicle had 1.5K miles only on it. Therefore, i am ok with saving $3K-$5K all day. Because new car would have been window sticker plus tax etc. also they are very friendly. The guy in the front knows how to work magic

Steven David Benzel Busch
I rarely write reviews and for the very few times I have done so in my life time, it was always to point out a bad service. HOWEVER. I had exceptional experience purchasing my E400 Coupe with Steven David from Benzel Busch. Since getting my first license back when I was 16, I bought and sold 10 different cars and Steven by far exceeded any of the sales person I have worked in the past. He was very responsive to all of my emails and phone calls. I almost got a reply back within 5 minutes from sending an email and we had many emails back and forth as I was purchasing a vehicle out of state. He was very detailed and truthful when describing a vehicle that I was purchasing. There were few times where he reached out to me first on items normally you wouldn't expect sales person to. Thank you, Hyunbin

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.

Nice Job
Getting your car serviced from anywhere you never know what to expect. At this dealership everything went smooth and easy from the appointment to my car getting done. My service person Natalie Torres was very pleasant. When I came to pick up the car a day later she had all the paperwork I needed hassle free with a friendly smile it's so nice to see that nowadays.

A very friendly and honest team .
I brought my BMW X5 from this place I must say my experience with these guys especially Branden was very professional, I found these guys has being trust worthy and very cooperative the went beyond the closing time to make sure I got my vehicle the very day even though I got there around 1& 1/2 hour before closing time ...I got there @ around 6:25 pm and the was supposed to closed @8pm...Thanks to Branden and José ( I hope I got his name right) And finally and most importantly the price that the advertised for their vehicle will be the price you will pay , not like others who will tell you the advertised price is after you pay down 20%..I will definitely recommend North Star Mitsubishi to you.

Excellent selection and service
I would highly recommend working with Ralph Rodriquez at Mercedes-Benz of White Plains. He is very knowledgable about the brand and models but isn't pushy. He made the buying process super simple and valued my time. The dealership has a good selection of certified pre-owned cars at excellent prices.
