Our Reviews
We came from out of town to visit this dealership and it was worth the drive. Rudy and Alex were super friendly and helpful! We love our new car!
I was able to easily schedule my appointment last minute. My wait time was reasonable and the price for the work was in-line with my expectation. I will say I have had Lupe as my service advisor multiple times and he continues to kill it with outstanding customer service!!
Fantastic people
I had a really great experience working with salesman Jim Cullom. It was my first time buying a car by myself and it was an emergency situation but Jim was so kind and reassuring. The places I went first were pushy and made me feel annoyed and anxious. Jim was the opposite not pushy at all and really listened to what I was looking for to help me find the best option. He let me have plenty of time to test drive the car on my own also to help me feel more confident about it without any pressure. If I had to buy another car I would definitely want to work with Jim again and would be happy to recommend him to others.
Service was timely, kept me informed all through the service process, prices were reasonable, everything was exceptional!
Looking at new cars the Buick envision was are favorite. John was very helpful and not rushing us with a decision. Very happy with results.
I have been a Cadillac owner since 1979 and I have never been treated as special as I was at Fox Valley Buick. John went above and beyond to explain things and make sure I understood. I was really impressed!
John was the best Sales-guy I have ever met, he was not pushy, treated us excellently and was transparent when it came to Numbers Sam
Everyone was very helpful throughout the whole process. Very friendly and professional. I would recommend this dealership to anyone looking to buy a GMC
Best car buying experience. Mike was amazing, attentive, and very easy going keeping the process calm and relaxing.
John Cordova is honest and quite knowledgeable about the Buick Envision. He made an effort to find all rebates for which we were eligible.
I have been customer of the Fox Valley Group 10 plus years. Have referred family & friends. John Cornova & frank Butahu took good care me. Purchase new Denali pick up.
I ordered a Lexus from Minnesota and traveled to Saint Charles, Il to complete the papers work and get my car. All the process went smoothly, they sent one guy to give me a ride from the airport to their office. I appreciated the hospitality and professionalism. It was nice working with the Fox Valley guys.
This is the 4th vehicle we have purchased from Fox Valley Auto Group. And the reason why is because we have always been able to get the vehicle at a fair price, the people we have dealt with in the sales and service department have been very nice and explained everything. We have purchased 2 Buicks and 2 GMC's at Fox Valley Auto Group. And we will probably purchase another vehicle from them when the time comes.
Excellent service. Knowledgeable people and very friendly and positive staff. I will definitely recommend. Thanks
Frank is a superstar. An excellent experience from beginning to end.
Took my truck here since i had horrible service at Woodys in naperville & wow was i glad to make the drive , everything went well , Frank kept me updated and got my truck back to me the next day! Will continue coming here only as they’ve earned my business!
Service was thorough
The team of Mike Hampel (Sales), Greg Kostelny (Manager)and John Cordova (Finance) exceeded all of my expectations and made my purchasing experience a great one. From start to finish Mike Hampel was understanding, compassionate and helpful with this transaction and he’s still helping me out setting up all the new tech items. Big kudos to this team!
I wanted to do this review and to thank Mike Campbell for being the best salesman ever. He was a great help and any problem I had, he made sure it was taking care of .I would definitely do business with him and Fox valley gmc again. Thanks Mike C!!!!!!!!
Made my process super simple and I expect anything but. Was extremely stressed about my totalled vehicle, but Mike and Alex made the entire process seemless. Both were great to work with and personable thru out the long process
Honestly we were very anxious coming in. We had stressful situation trying to get my daughter into a car after an accident and only had a limited amount of time before I had to go home out of state. I think Mike could see how stressed we were and took extra time to take it slow and walk us thru it all. He led us to car that I think works well for her situation. Alex also gave us all the answers we needed regarding financing and proper coverages. They just seemed to care about what our challenges were that day. That weekend was crazy with a move too. So thank you
Thank you FVBGMC Team for all your help again providing me options to upgrade to a new truck with all the latest safety features! Thanks to Josh in Sales, Greg the GM and Alex in Finance. I appreciate all you did to help make it happen.
Josh in sales was very informative on the vehicles systems and talked us through various features. He was friendly and easy to talk with. Made us feel very comfortable so that buying experience was enjoyable.
John Cordova and team were great. The truck I put a deposit on was delayed by the manufacturer. John was very open and honest in his communication with me. Alex in the F&I was a pleasure as well. One of the best car buying experiences I’ve ever had.
