Used Audi A6 sedans for sale near Hazel Crest, IL

I cried about the price of my tires but to know they are covered was a big load off my shoylders

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!

Sam provided me with the best service experience , good prices, explained how things go in my car , I have zero experience with cars, he went out of his way to explain everything for me and made things clear

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

I just purchased a car from Castle Hyundai of Oak Lawn, and I couldn’t be more grateful for the experience. From start to finish, the team showed true professionalism, care, and integrity—qualities that can be hard to come by in the car-buying world. Now I truly understand what they mean when they say “Drive Happy!” Jim (Sales Manager), Nick (Sales Consultant), Brennan (Internet Representative), and John (Finance Manager) were an absolute pleasure to work with. They went above and beyond to make sure I felt informed, respected, and supported throughout the process. They were transparent, never pushy, and always willing to answer my (many!) questions with patience and honesty. It was clear that they genuinely cared—about the car, the deal, and most importantly, about me as a customer. They didn’t just meet expectations - they exceeded them. The entire process was smooth, respectful, and even enjoyable. These are good people who take pride in doing right by others. Thank you to everyone at Castle Hyundai of Oak Lawn—you didn’t just help me get a great car, you made the whole experience one to remember. You went the extra mile (pun absolutely intended) and because of you, I now Drive Happy!

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!

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

Cheyenne Fontanez is the best! This process started back in March of 2025 when I was gone for the winter and she stayed in contact with me until we got a deal done on 10/8! It was a seamless process and I couldn’t be happier!

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

Mike R was amazing. He even traveled to Chicago to bring our car to a different locations so we could see it. I would highly recommend this location.

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.

We just bought a high mileage TESLA from star motors. The entire experience and the car itself was great. Alex can actions as very reliable, open and ready to help always. Payment and shipping were managed in a very honest and trustworthy manner.

The new design is awesome. The size of the car is perfect. Leges room is so good and the screens in the dashboard looks fantastic

Excellent experience this past weekend. JC was very helpful during the entire process. Highly recommended

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.

Wide selection and no haggle are a plus over other dealerships. I like being able to see how many different makes and models. CarMax is the only place I will shop

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.

Awesome service from Jose!!! Very patient and kind. Explained every detail. All dealerships need a Jose!

The car meets my needs for the next few years. I’m happy with the handling and the gas mileage so far. I’m satisfied with all the features and the car is comfortable and easy to drive.

They had what I was looking for. Went to go check it out, it was the best condition & price out of all the cars I had checked & there process with paperwork was quick & easy. Highly recommend!

My uncle had recommended me to them as he’s purchased many cars before with Baha. Nas and Mayra were super informative and helpful. This was my first time buying a car so i was super stressed but they made the whole process a breeze.

The comfort level, the interior and exterior, the wheels, rims all are in great condition. I really like this car. Best Purchase ever!! Good place to buy a car.

Know how to work with customers always giving deals on service. In service department. A one.

Just what I was looking for. All the safety and technology combined with special features that make driving special again. A very special automobile for my family

I had my Outlander serviced at this location and they were able to help us out with great discounts and promotion deals. I am very grateful and highly recommend coming to this location for car services.

I was given plenty of time to find without any hassle or hard selling. It made the whole experience feel relaxed and enjoyable rather than rushed. Any questions I did have were answered clearly and honestly, and I never felt like I was being pushed toward something that wasn’t right for me. Arranging the test drive was quick and simple, and the test drive itself was smooth. Everything was explained clearly, and I was given the time I needed to properly get a feel for the car.

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.

Wonderful buying experience Kimmy was so helpful and nice as could be loving the new Audi wagon

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.

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.

The experience was outstanding, the salesman answered all of my questions and made the process of purchasing this vehicle a pleasurable experience.

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.

Paul was great, made the whole process a breeze. Super knowledgeable and helped me get my A4 Quattro. Highly recommend!

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.

A wonderful luxury sedan that is beautiful and quick!!! We returned home [Denver to TN] and after having driven over 1200 miles, car seemed to get almost 31 mpg on average.
