Service rep was very attentive as I described the issue
Service rep was very attentive as I described the issue with my Q8. Car was given a multi point inspection and washed. Fault was cleared and everything looks good.
Must buy at a realistic price.
Such a gorgeous vehicle, inside and out. Haven’t had a single issue with it for over a year of having it used. Inside of the vehicle is super roomy, and driving feels very comfortable, and really we’ll insulated!

Good experience here.
Good experience here. Was in the market for a used BMW 5 series and came across a dark blue one at this location. The interior was beige like I wanted. I was a little concerned with the financing part but Robert got me a good rate. Car is exactly what I hoped it would be.

The salesperson, Hailey, was pleasure to work with and it was a no pressure sales. I feel I got a great used vehicle for the money. Thank you, Hailey.

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
Perfect sports sedan, TDI engine is amazing!
Bought my '16 A6 3.0 TDI a year ago with 89k miles, now has almost 110k miles, and drives like a dream still. Can't even tell it's a diesel engine by the way it drives and how quiet it is. I drive a lot for work, and the gas mileage is amazing! Interior is comfy, classy, and roomy. Drives like butter, handles like a sports car. Exterior isn't too flashy, it's perfect. No issues, and my last checkup at the German export dealer was perfect. My favorite car I've owned, now I want an A8 L!

Excellent choice
This is a fun, responsive, reliable, well built car to drive. At over 75K miles now, and I really cannot even consider trading it in because I don't think I will enjoy a better ride.

Very good car eventually
Initially had problems with the front brake rotors. Audi replace them twice, but did not replace the pads. Turned out the pads should have been replaced with the rotors because the pads just transferred material onto the new rotors causing the braking shimmy to return. I paid for new pads on the second rotor replacement - problem solved. Audi could have saved money (and saved me money) by just replacing the pads and rotors the first time. After this, the car was great. Very comfortable, and quick. Gas mileage was very good - about 19 MPG in town and over 30 MPG highway with the 6 -Cyl. due to cylinder cutout when crusing.

Amazing manager and team! Super trustworthy place. Great deals and great price! Thanks John for your time and your help in finding me the right car!
A great certified pre-owned car fully loaded.
This car is amazing. Two of my family members are audi fans so I decided to buy one for myself. Certified pre-owned is definitely the way to go. The interior and exterior are absolutely gorgeous and the ride and comfort is excellent.

Great process all around. Everything that needed from financing to every last detail of paperwork they helped with. I'll be coming to get my next car from them.
Pure luxury
This Audi is beautiful, inside and out, with genuine wood in the door panels, dash and center console, soft leather seats, and a massive amount of red light illumination throughout the front cockpit, that is fantastic while driving at night. The exterior is sleek and stylish. The ride is smooth, however the low profile tires do ruin some of the ride atleast on kansas roads that are far from smooth. The engine has no vibrations and suspension seems tight . All in all this is as close to perfection as it gets, German cars are the best.

Great experience
On October 28th I went to prestige lexus of Ramsey in new jersey.I met with a sale associate by the name of Steven Glenwick who provided excellent customer service he was patient, attentive ,informative. Steven went above and beyond to assist me in selecting my future vehicle. Everyone that assisted me that day were very professional and made me feel comfortable with my choice. I highly recommend Prestige lexus of Ramsey for anyone who is looking to purchase a vehicle. Thank you Marlene.

Holman was a great salesman,very attentive and helpful was a nice chrysler 300!!!! I appreciate it
My favorite car out of the over 17 that I’ve owned
An truly amazing car with the best technology I have ever seen in an automobile. I am an electrical engineer so I don’t make that claim lightly. The best engineered car I have ever owned. I look forward to driving it whenever I need to go somewhere - a powerful comfortable car that can compete with cars costing much more.

I seriously cannot recommend Audi Englewood enough.
I seriously cannot recommend Audi Englewood enough. I worked with Anna for a car for both my wife and daughter and she was honestly incredible from start to finish. She made the whole process so easy and stress free. You can tell right away she genuinely cares and isn’t just trying to sell you something, she actually listens and wants to make sure you’re getting what’s right for you as a customer. She was super knowledgeable, super patient, and just helped me feel really taken care of and find ideal vehicles for my family. The whole vibe at the dealership is just the same, everyone is friendly, helpful, and just wants to make sure you leave happy. If you’re thinking about getting an Audi, seriously go to Audi Englewood and ask for Anna. I can’t recommend this dealership enough! You’ll be glad you did. 10/10.
Best car i have owned.
This car is luxurious and sporty. Everything you want in a car. It is the best car I have owned so far. I am very happy with it. I just had the 30K service. It was expensive, but its Audi. You get what you pay for.

Quattro Manual Fun
Quattro holds the corners like no other car I have driven hard! 2.0T tuned to 300hp with a manual transmission is just fun. No deed to get the S model. But may want the avant wagon A4 for the family or even A6.
