Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

I had the pleasure of working with Jeffrey Serwas at
I had the pleasure of working with Jeffrey Serwas at Advantage Chevrolet of Hodgkins & Countryside, and I was genuinely impressed. He was professional, personable, and made me feel welcomed—like I was a regular, part of the family. He took my concerns seriously and made sure I felt heard and valued. I don’t usually like name-dropping dealerships, but I have to be honest. I purchased two fully loaded Suburbans from Castle Chevy North, and yet, I still don’t feel welcomed or appreciated there. I barely get a proper greeting and often feel like a bother rather than a valued customer. The level of service and hospitality at Advantage is truly above reproach. Even though it’s a further drive for me, I will gladly make the trip just to work with Jeffrey moving forward. Thank you for such a refreshing and professional experience.

I love the new facility, waiting for my car was very pleasant. The service rep was great, took care checking me in and my car was ready quickly, they even washed it. Thank you as always, this is my 3rd car purchase with you but my first time buying the care package...happy I did.
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

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.
Exactly what I wanted.
I absolutely love my vehicle. It is reliable and comfortable. I recommend this vehicle to anyone that wants an SUV and is looking for a change.
