I want to note this dealership as one of the best, with flexible prices and professional staff. I especially want to note sales guides: Agnes Landowski and Dennis Azarov. They have proven themselves not only as good advisors in financial matters but also as experts in the technical features of cars.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

Wonderful Car Purchase Experience!
The sales team members were so eager to help make my car purchase an enjoyable experience! Diana, the Internet Sales Specialist, was very friendly and helpful. She helped coordinate everything with the sales team perfectly! They sent videos of the car I liked. They were very friendly when I had the car inspected by an independent mechanic. When we agreed on a fair price, the sales manager delivered my new car and took my trade-in car back to the dealership! We completed the paperwork in five minutes at my home. It was such an easy and enjoyable purchase experience. I contacted several Nissan dealerships in the area and Hawk Nissan was the absolute best!! I would highly recommend this dealership!

This was by far the best car buying experience EVER!
This was by far the best car buying experience EVER! Victor was professional , prompt and made sure our transaction ran smooth from start to finish ! Victor took extra time to show us all the cool features our new Toyota Corolla has. The finance guy made sure we got the best rate and helped us find the best deal for an extended warranty. Can not say enough good things about this dealership and the entire team at West Chicago auto mall

We recently purchased a car from Your Choice Autos, and the entire experience was genuinely outstanding from start to finish. From the moment we walked in, we felt welcomed and taken care of. Our salesman was incredibly informative, and attentive to everything we said or asked. He took the time to really listen to our needs, answered every question thoroughly, and made sure we understood each step of the process. What stood out most was how smoothly everything went. There was no pressure, no confusion—just honest guidance and a clear commitment to helping us find the right vehicle. He made the entire experience feel easy and stress-free, which is something we truly appreciate when making such a big purchase. We wouldn’t hesitate to recommend them to anyone looking for a quality vehicle and a dealership that truly puts its customers first.
