Used Audi A6 for sale near Geneva, IL under $899,990

On August 9th, 2025, a family member requested my assistance in purchasing a car at McGrath Acura dealership in Westmont, Illinois. Our salesperson George provided exceptional support and enthusiasm throughout the process. Although the exact color we desired was not available, George diligently demonstrated alternative options while his manager searched for the desired vehicle. Their joint efforts culminated in a remarkable outcome. After careful consideration and negotiation, we ultimately selected the available alternative. The conversation with George, the manager, and George, our sales representative, was highly enjoyable. Both individuals demonstrated expertise and provided comprehensive answers to our inquiries. They genuinely prioritized our satisfaction. I highly recommend McGrath Acura to anyone seeking an Acura vehicle. Make sure to talk to George in sales!

We started out knowing what car we would like to test drive. From the moment we walked in the door we received a warm welcome and everyone we met was extremely nice and wanted to help. The only annoyance, and it really is unavoidable, is the amount of time from beginning to end it takes to purchase a car. Our salesman, Mark, was knowledgeable and informative, helpful and honest and engaging. Would highly recommend him.

Excellent car, just done 122K and runs like a dream, had it serviced regular by brilliant guys at the general motor company in Stockport in UK. Didn't want to trade in when lease finished. Looking to get many more miles Peter Gilligan

Max and Sam were very helpful and accommodating. Answered all my questions and provided information. I did a test drive and liked very much but eventually thought the vehicle might be a little bigger than I want or able to fit in my garage. I would definitely recommend Little House Of Cars.

The Interior leather brand new, comfort is what I need and Super roomy front and back, Truly a sleeper mid size luxury vehicle, very quiet til you switch to sport and that Beast of Super charger Will make you Hang, my 1st Awd. So time will tell nothing bad all new territory

AMAZING PLACE!!! I bought a 2021 Kia and I had it shipped to my house in Texas, extremely smooth process and it was a lot better than I expected it. Thank you Midway !! I will be back in the future!!!

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.

Great job in and out. IT'S been a good experience so I will let people know.

I have the A6 Avant, which is a large wagon with amazing power and surprising reliability. It's the nicest and most comfortable car I've ever owned.

Great follow up, I haven't at this point found unit I was pleased enough to purchase. Thanks for your attention...........done

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.

Bought a 2009 BMW 3 Series 6 Months ago and wanted to review after I had the car for awhile. I wasn't sure buying from a smaller dealer, but everything worked out and the car is still running great. I would definitely recommend buying from this dealer. Thank You Max!

Very comfortable and reliable car. Great for road trips or around town. comfortable to drive and grab gas mileage. one of the best cars I have owned.

Karl here at rides unlimited was beyond helpful on our buying experience. He was able to somehow Get us down to the price range we wanted and worked on the overall price the whole time. Even when we thought we had what we thought was the best deal he continued to work and somehow found us something even better. The selection here has something for every price range and the staff goes above and beyond.

I bought my audi a6 quatro s line 3ltr tdi automatic 2010 just under a year ago have had regular servicing and 2 new front tyres, just passed its mot last week, all it needed was two new front bushes, total cost £120-00,I have put just under 40 000 miles on clock since having her, never missed a beat, a few minor things such as wiper blades, rear boot lid struts but all in all, a very reliable comfortable loverly vehicle, and yes, I most certainly will be getting another

Talked on the phone, and the second I walked in, very laid back and honest people, best car buying experience I’ve had, Ryan and the whole crew in there are amazing!

I have owned this car for just over a year. No mechanical problems, very fun to drive. Took it across the country, very comfortable for driver and passenger. Loves to cruise at 75-85 mph and will go much faster. I thought I got a great deal on it. I paid half the sticker price and it had under 10,000 miles on it.

⭐️⭐️⭐️⭐️⭐️ 5 stars all the way for Quick Sales! If you’re looking for a dealership that actually stands by their word, look no further. I recently bought a 2014 Toyota Prius from Quick Sales, and from start to finish, the experience was top-notch. Ralph, the manager, is the kind of guy you hope to deal with when making a big purchase. He promised to replace the missing headrests on my car—and not only did he follow through, he went above and beyond by also sending a crucial part needed for my airbags. That level of integrity and follow-through is rare in the auto sales world. The transaction was smooth, the communication was clear, and Ralph made sure I felt confident and cared for even after the sale. It’s not just about selling cars at Quick Sales—it’s about building trust. I’m beyond satisfied with my purchase and the service I received. If you’re on the fence about where to go, let me save you the trouble: Quick Sales is the real deal. Five stars all the way!

This car was absolutely amazing to own and drive. From the slick exterior style, to the classy interior design. Jaw dropping. Many people will mistaken it for a newer model as well. Great drive. Very smooth, and strong. Highly recommend.

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

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!

I had a great experience at Hoffman estate Audi they were knowledgeable about there vehicles and the buying experience was hassle free thanks to Carlo I would definitely recommend this dealership.

The experience was totally Great the best dealership I’ve ever been to in my life.

I had an outstanding experience with Eryk Buczynski at Castle Volkswagen of Schaumburg. From the moment I walked in, Eryk was incredibly welcoming, knowledgeable, and genuinely focused on helping me find the perfect vehicle. He took the time to listen to my needs, answered all my questions with patience, and provided clear, transparent information about pricing, options, and financing. What stood out most was Eryk’s dedication to ensuring I felt comfortable and confident with my decision. He guided me through the features of the car, demonstrated how everything worked, and followed up afterward to make sure I was enjoying my new vehicle. The entire process was smooth, efficient, and stress-free. If you’re shopping for a new or used vehicle in the Schaumburg area, I highly recommend asking for Eryk. His professionalism, integrity, and customer-first approach truly set him apart. Castle Volkswagen of Schaumburg is fortunate to have him on the team. Thank you, Eryk, for a fantastic car-buying experience!

The car is pretty much what I was looking for. Enough space for the family; fun and exciting when I needed to be; practical and reliable all other time.

Honestly, the best customer service experience. Jason really understood my non-negotiable wants. Worked out perfectly! Thanks!

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!

Very professional and helpful. Also, the salesperson was very helpful and accommodating. I'm happy to recommend!

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.

Pleasant and understanding vehicle unfortunately didn’t meet my expectations Martin was great very pleasant.

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.

Great selection of cars and great prices recommend I bought a 2024 Kia ev9 ask for Joe for the best experience!!!

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.

What a great team, very impressed with the service and effort they put into getting me in my new Jeep. Thank you Kunes Family

I love this car. Audi is the best looking car. I got Tango red metallic with black interior . When you open the door Audi rings light up so you can see better in dark
