Our Reviews
My husband and I are frequent customers of Fox Valley Buick GMC. We keep returning for their excellent customer service, and their friendly and knowledgeable staff. We were very happy with Rudy on our recent purchase!
Great experience. Patient and friendly service. Rudy great and showed us the options we asked for and was patient understanding while we talked in private about options and decisions. Happy experience!
While waiting for our oil change, we saw a truck we liked on display. Rudy greeted us and was super helpful. He is very knowledgeable and not overly aggressive. Thank you for the easy buying experience.
Rudy was a very knowledgeable and helpful salesman. He was very friendly and welcoming. Rudy, Frank, and Alex all went above and beyond to make us very happy customers. Would recommend and will encourage my family and friends to visit this dealership again Toni St Charles resident
Great experience with Fox Valley GMC. Jason and John in sales and Alex in finance were all great to work with. All were helpful and very knowledgeable, not to mention friendly!
We were referred to Frank from friends that have bought cars from him for years. They would not go anywhere else. Frank set us up with Rudy. Rudy was very knowledgeable about all of the features of the different used cars we looked at. Since new cars are challenging to get at this time, Rudy was great at showing us different options and find the car that checked all of the boxes for us. He was able to educate us on what certified pre-owned is, as well as how warranties work for used cars and things to consider on maintaining resale value since we do plan to buy a new car in the next year or so. We are very satisfied with our purchase and will be back for a new car once new car inventory improves including chips for the luxury of heated seats and steering wheels (I am not willing to go without these in our Illinois winters)!
I had some initial reservations about dealing with such a young salesman, but Josh immediately showed his expertise by listening to and taking the time to understand what truly was important and more importantly what was NOT important to me in my search for my next car. He laid out my options and continued to look for a unit that best fit my criteria. Of all the cars I have ever owned this was the most pleasurable buying experience I ever had. In the future I would only buy my vehicle from Josh!! Also, Joe in Finance was excellent as well. Straight and to the point, he listened to me and acted accordingly.
Rudy was great! he was very friendly and knowledgeable. Highly recommend him and Fox Valley Buick
Rudy E. was great to work with and provided excellent customer service! The SUV we asked him about checked all our boxes and the rest of their staff was great to work with as well. I highly recommend Rudy and their staff if you're looking for another vehicle.
Bought our second new car from Fox Valley with the salesman Rudy E. Extremely easy to work with and got the vehicle we wanted at the right price! Love these guys.
I enjoyed working with them. They’re very professional and got me in and out in a timely manner.
Rudy and Alex were excellent!! Very professional. Thank you so much love my new car. Made the process easy.
I love my new car! Thank you so much to Rudy E. for going above and beyond for us in a Covid 19 world. He was clean, efficient, and professional. If you need a car quickly and covid free, then Rudy is your guy.
Wow. Rudy was exceptional and so helpful. He listened to our needs and help us find the right vehicle for us! In all my years of buying autos, he was by far the best sales consultant we’ve done business with!
Rudy was great. He was very responsive to all our questions and had excellent knowledge of the cars, services and the buying process.
Rudy is the best salesperson I ever met. We'll ask for him always. Thanks Fox Valley Buick GMC. I love my Buick SUV GMC are nice too. I came to look at a Acura and Chevy and Ford, but I'm super excited about my Buick. Thanks again Rudy.
I have already given my review on my salesman Scott previously who I feel is the best. I would also like to give a shout out to Alex Katselis, Finance Mgr. Alex too was exceptional. He did a great job processing the financing with ease. Thank you Alex.
Best experience ever with Scott Frank and Fox Valley Buick dealership. Scott was very knowledgeable and professional and is a real asset to the company. Definitely would recommend Scott as your salesman.
I live 4 hours away but made the trip to Fox Valley because they had the exact truck I wanted and at a great price. Joe was super helpful and sent extra pictures in advance and took time to answer all my questions to make sure it wasn't a wasted trip. When I got there the truck was exactly as he presented it. Joe was personable and professional and made the experience great. Best car buying experience I've had!
It's my first time buying a car so my clueless self, walked in there super confused and stupefied. Brought my middle aged Asian mother along who had so much to say about things she didn't understand either. So they had to deal with me taking forever to translate and go back and forth. Bryan is my new favorite person, thanks for dealing with me.
This was the best experience I have ever had when buying a used car. Michael did everything possible to give us a GREAT price for a GREAT vehicle! He takes care of his customers!
I brought my Buick Encore in for minor repair and I ,worked with Scott Frank. Service was great. I was given a loaner car which was very helpful. I highly recommend Fox Valley GMC.
My husband had purchased a GMC Terrain a few months prior to my purchase of the Buick Encore. Did not want to give up my Saturn Vue but it was ten years old. Our experience with Scott during the purchase of the Terrain was so easy I knew he was the one to see for another vehicle. He did not disappoint. Great experience! Great price! Highly recommend!
I had been looking for a car to replace my old, passed down vehicle. As a first time buyer, I was nervous to be faced with the rush of pushy sales people. After going to a couple of different dealerships and having experiences that only made me more anxious, I went to Fox Valley Buick GMC. There I was met by a salesman, Mike Aiello. I instantly felt at ease and as if I were talking with a friend. Mike was very kind, informative, and easy going. I never felt pressured or rushed in any decisions while dealing with Mike. I appreciated his patience through all my questions and indecisiveness. Mike made sure I was getting exactly what I wanted without exceeding my price limit. His dedication to helping me as a customer was exceptional and his personable demeanor made my first time buying experience stress-free!
Scott was an amazing salesman when I bought my Encore. Professional and knowledgeable, you can tell he is passionate about his job and cares about his customers. I wouldn’t go to another person for a car. I refer all my friends and family to him and I will be back to purchase my next car from him. The managers and dealership were nicer well kept and professional as well.
