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!

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.

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.

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

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.

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.

Jeff Liszka was wonderful to work with! He kept me up to speed on time it would take for the service when a glitch came up with the recall and called me directly when it was ready for pick up. Nice and easy experience.

I had a fantastic experience purchasing my vehicle at Audi Westmont. From the moment I walked in, I was greeted warmly and introduced to Nikola G., who was exceptional to work with. I explained exactly what I was looking for, and Nikola delivered perfectly. He was incredibly knowledgeable, walking me through the performance and features of the vehicle in great detail. The entire process was seamless, and I walked away feeling like I got a GREAT deal. I also want to give a big shout out to Gianfranco in Finance; he was thorough, friendly, and made the final paperwork quick and easy. If you are looking for a new Audi, I highly recommend visiting this team!

I had a great experience with them! They made the process very easy and even gave me a better rate than my own credit union, which I've been with for over five years. I highly recommend them to anyone looking for excellent service and competitive rates. Thank you!

Great service and easy to work with. In and out quickly and they had a great selection of imports.

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

Brandon and the Manager were very helpful in helping me finding the right car for me.
