Shout out to Genesis for helping us get our dream car , she was very honest , helpful , charismatic ! Anyone will like to buy a Car from her , and she did every single think to make sure my car was clean and in good condition . Also I love my car very comfortable.

We always have a great experience at this dealership! Bobby has consistently taken amazing care of us over the years, and we couldn’t be more grateful. Sally Morshed and Seth have also been exceptional throughout every step of the process—professional, attentive, and genuinely helpful. What really sets this group apart is their honesty and integrity. They’re not just trying to sell us something—they truly care about doing what’s right, even in today’s world where costs are rising everywhere. We sincerely appreciate the time, effort, and genuine care they put into every visit. A fantastic team all around!

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Overall great experience. Salesman Jean was great to work with. Got a lower price than I was expecting and am very happy with my car

I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

Jeremy was fantastic to work with, transparent and committed to providing all the information I needed to make an informed decision. My experience purchasing a Mercedes-Benz C-Class C 300 at CPM was stress-free. If you're looking for a dealership that prioritizes customer satisfaction, I highly recommend CPM.

I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

It was great I didn't feel pressure by the sales person Can you inform me of a lot of things I didn't know made me Trust the information he was giving me

This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

It has been a pleasure working alongside Carlos at stream auto. He and his team made it an easy smooth transition for me to leave there with a great car and a smile on my face thanks again team five stars to Carlos

I had such a great experience, everything was so smooth and easy, thank you Jim

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

After searching for over two weeks, I finally purchased a 2023 Toyota Camry as my first car—and C&K made the process smoother than I ever could have imagined! The team was knowledgeable, transparent, and answered all of my questions without any pressure. Best of all, there were no outrageous or hidden fees. I couldn’t be happier with my experience and would absolutely recommend C&K to anyone looking for a car!

The Acura team is thorough and I've never had a problem after any service. I'm glad the car wash machine was up and running as that and a vacuuming is a nice perk!

Very friendly family owned auto dealership. Dave were very accommodating with our situation and gave us a fantastic car at a great price.

Folks were very nice. Just did not find the right car there. Test drove a couple cars but none worked out for what I was looking for.

I had a highly positive experience purchasing my BMW X5 at Victory Mitsubishi with salesperson Derek and his team. He was very helpful, courteous, and professional. I plan to purchase my next vehicle here when my 16-year-old obtains their driver's license.

Absolutely amazing as always! Made a quick call with Miss T at Front Desk, she got the Service Dept ASAP for an appointment for change on a flat/damaged tire with Dani, in Service. Giovanni helped with the process all the while I was there. He kept constant updates with me on how the car is being managed and how long it will take. Knowing my kids and I outgrew the current A4, I lease with Audi Jack Daniels Upper Saddle River, I gave it a try to browse a bigger car with them. Adam Z in Finance, (super cool guy!) with whom I worked last time to lease my current car, introduced me to Anna Aslanian in Sales and Carlos in Finance. They all worked with me on the best car option and the best monthly lease rate. The entire team just made my day! I drove in to change the spare tire with a new one (NYC - fix the potholes on GWB please!) and I drive out of the dealership with a 2022 Q5! Again, absolutely friendly and courteous, seamless service as always! Thank you Anna, Adam, Carlos, Miss T, Giovanni, Dani and everyone involved! Now I have the new Q5 for a week already and can't wait to drive it out a 2nd weekend in a row Upstate NY! The car runs smooth, we all feel safe in it, I'm very happy to stay with Audi and always feels like home when I drop by the Jack Daniels Upper Saddle River Dealrship! THANK YOU All :) <3 <3 <3 Gigi

Quick response and knowledge in answering all my questions. Unfortunately, the vehicle I was interested in purchasing was sold.

I had an outstanding experience at the Mercedes-Benz dealership thanks to Albert Salib. His professionalism, deep product knowledge, and genuine commitment to helping me find the perfect car at a great price made the entire process seamless. Albert went above and beyond, and I couldn't be happier with my purchase. Highly recommend working with him!

Excellent service. Great place. Great people. Fresh coffee and muffins, bagels etc. They take care of you like a family. Carlos is the best.

Mr ANTHONY ANGELO was the best customer service we have experienced in quite a while. REPRESENTATIVES of this nature should be commended and placed in charge of that department .EXCELLENT CUSTOMER SERVICE!
