Agent Keith greeted me when I pulled in for service.
Agent Keith greeted me when I pulled in for service. He asked me to step inside and would be there in a minute after checking my VIN and mileage. He helped me locate my rewards number on my phone and went over the prices for my oil change, tire rotation and new battery. Later when I was in the waiting area, Keith informed me that 30,000 mile maintenance needed attention. I agreed to the two services recommended and was still out of the dealership in around two and a half hours. Keith processed my 10% discount and informed me of a $20 rebate for the new battery. He explained the process for requesting the rebate online. I highly recommend Garber Chevy for their sales and service. I have bought three cars here and am willing to drive the seven miles to Garber even though there are Chevy dealers in Lansing, Ill where I live that I no longer deal with if possible. The other dealership will always ask me three to four times if I would like to trade my car in or do I want to look at new car models. I don't like that, if I want to look at a car or want a trade-in, I'll ask. Go see Garber and you will be surprised!
I had my 2020 Terrain for 5 years before I had any major
I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

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.
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.

Great dealership with a friendly staff.
Great dealership with a friendly staff. Worked with us to supply a temporary car until ours was ready and followed up to make sure everything was ok.
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.

Rizza GMCCadillac see Coach
We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

After visiting a different dealership where we felt
After visiting a different dealership where we felt completely overlooked, working with Ali was a breath of fresh air. From the moment we pulled into the lot, Ali greeted us warmly with a smile and a genuine sense of welcome. His approach was never pushy—instead, he was thoughtful, patient, and fully committed to understanding our needs. Ali took the time to truly listen and provided us with a personalized selection of vehicles that matched our preferences and priorities. This saved us an incredible amount of time and helped us focus on what really mattered. He was also impressively organized, having paperwork ready in advance and maintaining excellent communication every step of the way. What stood out most about Ali was not just his knowledge of the vehicles and their features, but the way he worked to ensure we received the best overall value. He proactively reviewed all available incentives and savings opportunities, including several we weren’t even aware existed. He took the initiative to ask meaningful questions, like our professional backgrounds and ownership history, which led to valuable savings we wouldn’t have discovered otherwise. Ali’s service was sincere, thorough, and above all, customer-centered. He made us feel like we had someone in our corner, advocating for us—not just trying to make a sale. That level of care and integrity is rare, and we’re incredibly grateful for it. We wholeheartedly recommend Ali Abdullah to anyone looking for a car buying experience that is honest, efficient, and tailored to your needs. He made a potentially stressful process feel easy.
