I went in looking for a preowned vehicle and walked out with a new one. I felt more informed and much happier with the decision I made. Additionally I sat and thought about and was not pressured or rushed.
Comfortable and reliable.
This car has met my needs, comfortable, reliable, seems economic, nice exterior and interior design, easy to operate, my kids enjoy it. It’s overall very recommended.

Hi, My salesperson, Lyana was excellent.
Hi, My salesperson, Lyana was excellent. She was knowledgeable and pleasant. Looked us in the eye and answered all our questions. I would buy from her again.
Very nice upscale vehicle. Bought as a previously
Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

This was the best car buying experience in my entire life
This was the best car buying experience in my entire life and I bought few cars here and there. Cesar is an excellent and knowledgeable salesman and Sultan is a very good Finance Manager, taking into consideration my needs and not pushing the stuff I did not need. Thank you guys for making the purchase stress free and memorable. I did not rate the facility because it is under a renovation.
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!

Patty did a great job handling the 40k service.
Patty did a great job handling the 40k service. On time and budget as usual. Loaner car required advance notice (3-4 weeks). I’d like to see the phone system upgraded. I was stuck in the phone tree loop a couple times with no pickup or voicemail. Overall very happy.

Very satisfied customer
This dealership is comprised of a very accommodating, professional staff. Ali handled my transaction and performed services far beyond the average salesman duties. Linda handled the paper work which was very complicated due to my being a 100% disabled vet and entitled to special plates This is the first dealership I have encountered who knew how to process the asinine, paper work required by the DMV,[ dept. of mutual vilification ].
My second A6
My A6 2.0 quatro has 110k miles. Still looks great. Have gotten 34.5 mpg on open highways in Pa. Comfortable ride. Leather seats are holding up. This is my second A6.

Very professional , good prices and perfect location . My provider Klaled was very helpful and he really helped me taking the right decision . I am very happy with my car
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

Easy, smooth process!
Where do I begin?! This being my first time every purchasing a car, it was far easier than I expected! I expected a scary back-and-forth pressuring negotiation between myself and a tough salesperson, but NOPE! The whole process was much easier and went smoother than I thought it would be! I took interest on a car online and messaged the dealership through their website. I got a quick response from the internet sales team, under Cassandra Crawford. I had read previous reviews on her on Yelp and was glad she was the one who personally handled my purchase! All the positive reviews she previously received, I believe 100%! When I first stepped foot on the dealership to just take a look at the car in person, she gave me no added pressure to BUY NOW! She had a very kind employee (Eric) drive me to the expansion lot where I took time to admire the vehicle. We went back to the dealership and Cassandra gave me a quote printout with all the incentives and best offer to begin with and I walked right out that door feeling no sense of pressure put upon me! We continued to email each other for about a day until we got to where I wanted. From the beginning she asked me how much I wanted to pay for monthly and the down payment and she definitely delivered to meet all my demands! I told her from that I wanted to enjoy the vehicle and not regret it down the line all because of a spur of the moment big purchase. She understood that completely! In fact, I came by the next day to ask her further questions about the deal and that was it. Still no pressure to sign any contract or deal yet! I told her I'll be back tomorrow to sign everything and finalize the deal but mostly to sleep on it one last time (cold feet ��). She really worked with my work schedule to see when the best time was for me to come back. So, that was a total of 3 visits to the dealership (all my decision) and she was able to take time in her busy schedule to meet with me every single time. You can tell she is a very busy woman but she gets back to you on a very timely manner! We were even texting on her personal phone after office hours because I had so many questions for her (Sorry Cassandra!). Along with her assistant (also her daughter), they are able to work with you to meet all your needs! I told her that I would text her and let her know when the best time for me to come in was and with very short notice, she had everything all taken car of! When I got there for all the paperwork, my car was sitting right in front of the dealership, all clean and ready to go! Her daughter, helped me the technical details of the car and was very helpful! Frank, was the one who was nice enough to take time off from sales to help me start paperwork while Cassandra was at a doctor's appointment across the street. It was the only time I could swing by during work with a 3 hour window, so Cassandra was able to relay the information to Frank. Once Cassandra got back, she brought me over to Wayne who handled the finances. Wayne was another great associate who made sure to explain every little detail on what I was signing because I always have a lot of questions! He also worked with me to get the best deal possible on any extra maintenance packages I may need on the car! He was very honest on if I really needed a certain package or not and did not scare or pressure me at all into buying anything! The whole pick-up day process only took 1-1.5 hrs of my time and went very smoothly! ���� Do not go anywhere else if you are thinking about getting an Audi! Go straight to Cassandra! She will definitely take care of you! All the wonderful reviews on her on different websites are all accurate! Everything still feels unreal after a few sleepless nights because of pure excitement! Thanks again Cassandra Crawford! You're the best! Tell her Nathan sent you! ��
