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!
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

We bought a used Hyundai couple of weeks ago.
We bought a used Hyundai couple of weeks ago. I think we got a good deal. The dealership was a good experience, specially compared to the other places we had been to. The sales person Christian Gonzales was extremely friendly, helpful and cooperative. His manager Renato Garcia was also a nice person to work with.
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Price listed is the price you pay!
Dealt with this CarMax dealer over the phone and email. Tried to negotiate a price based on other dealers in the area for the same vehicle and was told that the price listed was the price you pay!
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.

On April 30th, I brought my 2018 Chevy Equinox to
On April 30th, I brought my 2018 Chevy Equinox to Advantage Chevrolet of Bolingbrook for routine maintenance and an oil change tire rotation. Their team of mechanics, Dylan specifically, and your service consultants Jimmy, Ray Jr. and Renee are truly exceptional, and I am immensely impressed by the level of professionalism and expertise I have experienced at your dealership throughout the years. Maintaining three Chevy vehicles can be quite a task, but the team at Advantage Chevrolet of Bolingbrook has consistently gone above and beyond to ensure that all of my cars are in top-notch condition. It's evident that they take pride in their work and are committed to delivering the best service possible. Their dedication to excellence has not gone unnoticed, and it has undoubtedly contributed to my continued trust in Advantage Chevrolet of Bolingbrook. I have peace of mind knowing that my vehicles are in the hands of experts who genuinely care about their customers. I?ve said it before and I?ll say it again, they?ve got a customer forever! Once again, I'd like to thank them for their exceptional service and for the peace of mind they provide as a trusted service provider. I look forward to continuing our partnership in the future. Jim McIlvain Downers Grove, IL.

The staff here is tremendous!
The staff here is tremendous! Not a single staff member walked by without acknowledging my wife or I. These guys know how to make someone feel welcomed here, the stigma of having a car salesman be pushy doesn’t exist here! Our sales man David Escobar helped us find the perfect suv and worked the perfect deal. Can not say enough good things about him, worked through everything, explained everything thoroughly and then some! Bottom line if you’re looking for a new vehicle and don’t want to deal with the drama this is your place to be without question.
