The Best!
We live in Jersey but made the drive out to Biener Audi because they have the best prices, selection, and reputation. Buying a car from them was so easy, and there were no tricks, games, or hidden fees. Their customer service didn't end once I drove off the lot - they have continued to provide great customer service, and I am now a loyal customer. Shout out to Leo and the rest of the crew for all their help!
Exceptional!

I had a fantastic experience at Audi Great Neck, thanks
I had a fantastic experience at Audi Great Neck, thanks to Kit! He was incredibly knowledgeable and made the entire process easy. The only problem I had was selecting the car I wanted because the dealership has a huge and possibly the best selection of pre-owned vehicles, and Kit went above and beyond to help me find the perfect fit. At the end of the purchase, I got to meet Ali, one of the directors at the dealership. Ali was very professional and ensured me that if I had any issues, he would see to it that all my issues are resolved. I Highly recommend Audi Great Neck for anyone looking for a car!
