Helped me get my first car!! Katie gave me a great experience 10/10 would recommend. Katie was very helpful throughout the whole process. Thank you

The vehicle we were originally looking at sold the same day we reached out but they worked with us on a great deal and even though we passed for now - we're definitely keeping them in mind.

Overall, I really like this car. Nice look inside and out. Easy to clean Internal cabin noise is quiet while driving. Like car notifications inside the car.

My recent service maintenance at Napoli Nissan was outstanding! Jeff, service adviser, was extremely helpful, courteous and professional. Jeff answered all my questions and concerns. I am a very happy Napoli Nissan customer. Thank You Very Much Jeff! John Maziarz

It saved my life I was in a bad car wreck a couple weeks ago in this car I hit a deer and drifted into a tree and flipped 5 times and the inside lit up to help me find my phone to call the police and my radio and steering wheel still worked to help call the police the inside was sturdy not one thing was crushed into the car definitely would recommend

I have the Limited. This is my 6th Hyundai/Genesis car and they just keep getting better. The technology is fantastic and equals many features in luxury cars at twice the price. In June I took a 3450 mile trip, hit 14 states and a variety of traffic conditions and it just kept chugging along with no effort. Features like HDA help on the long days of 700 miles. Used less gas than my previous car too, 95 gallons on that trip.

We have been leasing our vehicles at Advantage Hyundai for several years. We recently leased a new Tucson. Our sales advisor, Opal, was very helpful. Their service department is excellent. We highly recommend them. Carol & Jim

I bought my car as used from the dealer. I have had no issues so far with it. The radio and heater work better than my old Toyota Corolla.

I want to thank Mr Kier for the excellent and timely service. He performed a great job

I bought the car off a used car lot. It had $54,000 miles on it. I drove it to Louisiana and back and realized it was a half a quart low on oil. Took it back to the dealership and they can't find out what's wrong with it. But other than that overall experience is great.

So far so good ! We purchased two vehicles from this dealership and every time I had a problem they took care of it unlike other Hyundai dealerships in this area they don’t try to rip you off so far so good …

2023 Sonata limited. It’s a Fantastic car, especially for the money. It’s comfortable, stylish and efficient even with the high power. It’s a very nice car.

Miguel ramos the finance manager helps me with 2019 Mazda cx5 . I came recommend from a friend best service ever

This car was absolutely the best value for the dollar compared to the Accord Camry Mazda 6 and other Asian competitors this is my second Hyundai and these cars are well built reliable and an incredible value overall also a friend of mine is a mechanic and explains to me that these cars are easy to work on easy to diagnose easy to repair and parts are relatively inexpensive my opinion you cannot go wrong with a Hyundai

I just want to say thanks to Isiah Washington the manager of South Shore Hyundai for being a great and very helpful person, he always goes above and beyond to keep the clients coming back. Customer Service is excellent and I am very thankful to have someone like him managing, because he cares about the customers. He never let you leave dissatisfied. Kudos to Isiah and his wonderful staffs. A very satisfied customer 😀

I drove 3500 dually diesels for 25-30 years and then went to a Honda ridgeline 2018 new, love it until I drove my wife’s new car and decided I needed a car. My best friend had a Hyundai and loved it so I did hours of reviews Hyundai vs many others. All factors considered I decided to test drive a few. All things considered the Hyundai won and a low mileage 2021 caught my eye and I got it. After apps 1000 miles I am so glad I got it. Pros and cons Honda (H) push button start Hyundai (hy) key start, H remote start hy no remote start, H good ride hy better ride, H noisy hy less noisy,H electric keypad with gloves on more user friendly for me, hy parking easier, hy cornering better, H acceleration a bit stronger but hy smoother, both get the job done, I am 74 yo so I understand knobology better than the slow digital control for heat radio etc.,hy wins there- breaks equal, dashboard info hy wins, seems to love Google maps tolerates Waze, I prefer Waze. Pros and cons about not locking keys in car - can’t dash out start it w/o leaving key in ignition,physically gettin and out of the vehicle is harder, in a nutshell the things that matter more to me the hy wins so far.The salesman, Lamar was exceptional, a young family man earning a living by hustling but not rushing! Remember Lamar at Southern Auto Group in Newport News VA. Oh and the warranty was winner!

Great service amazing people ... Aderly was an amazing Sales Rep .... she has alot of patience and she was extremely helpful... Excellent Customer Service !!! I'll recommend City World of Hyundai any time any day. GREAT PEOPLE !!!!

Love my sonata! I traded in my older model and this is spectacular upgrade! Loving this auto . Sleek and very sexy design! Love the navigational design too!

Fantastic car, especially for the money. Drives, rides and handles like vehicles in a class above with firmness and solidity that’s never jarring. It’s comfortable, stylish and efficient even with the high power.

Very pleasant experience. No pressure to buy from Franklin Toribio. Profesional in his approach and how he treat his client. Will recommend to shop at dealer.

This is on a 2004 Sonota that has 191,000 miles. I bought it new and it has never been back to the dealership for a warranty issue. It has 2.7 v-6 and doesn’t use any oil between oil changes. This by far has been the best car I have ever owned. Good gas mileage, I’m 6’3” and has plenty of leg room. Yes I would buy another.

Our salesman, Ali, and other members of the staff were all knowledgeable, helpful and professional. We are very happy with our new Grand Cherokee Limited.

Owned our Sonata since October 2017, and it had 38k on it. Now it just clicked over 100k and it's been a great car so far! On a good day, I can get up to 44 MPG and about 25 city. Power is good (2.4 engine), tackles inclines well, and keeps up with traffic. Interior is well thought out and fairly comfortable. We just came back from a 3,300 mile summer road trip and had absolutely no issues! I do all my own maintenance which means it gets meticulously maintained. My #1 complaint is oil consumption. PLEASE CHECK YOUR OIL REGULARLY. If not, you can kiss your engine goodbye! Only issues I've had were two dead batteries but other than routine maintenance, I can believe that this car will achieve 200,000 miles! Take care of your car and it will take care of you!

Aug 15, 2025 I recently bought a used car that I found online. I got a written quotation upon request electronically as I requested. I took a very long ride to get there & was treated very well. Abraham Mata was very cooperative & professional throughout the entire process. I left the same day with the car. I’m very happy with the dealer & would recommend them. Richard Lindner

I love my Sonata. I drove an SUV for 16 years, and I was ready for a change, and it was the best change I could have ever made.

Service rep Jennifer was very professional; courteous; knowledgeable. Easy to deal with. Repairs made in a timely fashion. So far, i am happy with Napoli experience.

I've got a 2023 Sonata N Line, with 1800 miles on it now. It's a great car, for the money. Performance, style, comfort. It needs a memory seat for sure. The front seats mold to you but is very hard to get in and out of unless you move the seat back. Also, the inside needs much more storage space, center console is small, glove box is small, and side pockets are almost useless.

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

Great price great experience in delivery. Great buying experience. Will do business again. Top Shelf, sales and service team. 2nd buy from Family Hyundai. Five Star

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

I've had over 44 cars, trucks and Vans both Foreign and Domestic and this is the Best overall. I recommend this car to anyone presently looking for a Great Used car.

Amazing experience with both the salesman (Vic) and finance department. Vic was amazing. Courteous, helpful, absolutely no pressure or “up-sales”. Entire process took less than three hours. Highly recommend. Seamless experience. Thanks again Vic.

Bought the Sonata n line, the car is quick and looks great. Awesome gas mileage too for the performance you get out of it. All of that on regular gas. Fun full size sedan.

Rodrigo is great sales person i buy 3 cars from them good dealer no hiding fees

I purchaes my car new. And I love my car kept it service and it has been good to me. I have wsy over 100,000 miles and still going.

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

This 2018 is my second Sonata. Hyundai addressed all the issues I had with the 2012 I owned. All I've done is oil changes, brake pads, tires. The car has been flawless, the transmission is very smooth, though I liked the 2012 transmission slightly better for the shift strategy. Technology package is fantastic. Dynamic cruise, lane keep assist, auto emergency braking... Almost drives itself. The car is still humming along like a sewing machine today.
