Our Reviews
Mike was absolutely amazing!! We all managed to figure out a way for me to able to get my car and it was great! He was really helpful and explained everything really well and my parents and I were very thankful for all his hard work :)) I definitely recommend coming here as it was a good experience!!
Very pleasant from the moment I pulled into the garage until I pulled out of the lot.
Definitely not a fan of car shopping, but Mike at Fox Valley GMC made it super easy. Went in thinking I was just looking and left with exactly what I was looking for.
Josh was great! Answered all questions and concerns!
I bought my Prius there & they were great! Rudy was an amazing sell’s person. He wasn’t pushy & was very personable. I felt listened to and we’ll taken care of. Thanks Rudy!
Friendly staff Clean facility
Great customer service
Great staff! I bring both my cars for service at this location. They greet and treat their customers well.
Andrew is great. Also appreciate the text messages and access to information, paying online, etc. Your cashier at front desk is very efficient and detail oriented all the way up to requesting that the pen goes back in the cup.
Very happy with the excellent technical skills and customer service strengths of the whole repair and service team! Our regular mechanic at a different business tried twice to diagnose and fix a problem with our car's AC and defrost, but failed. So we came here. Problem was identified quickly; parts were in stock; and price estimate was reasonable. One of their porters (Mason) gave us a ride home so that we didn't have to wait for hours. Another porter (Alex) gave us a ride back when the repairs were finished. Really grateful not to have the expense of renting a car. Problem was fixed and we are thrilled. Definitely coming back!
I had a very pleasant experience purchasing a used vehicle from Mike Hampel. He was very courteous, friendly, knowledgeable, and genuinely cared about making me feel comfortable with the whole process of purchasing my vehicle. He was not pushy in any way and took the time to explain how all the bells and whistles worked on the Chevy Tahoe I was purchasing. I highly recommend Fox Valley GMC Buick and Mike Hampel if you are considering buying a new or used vehicle. Their entire staff is very friendly and curtious and make you feel comfortable. I would definitely purchase another vehicle from their dealership when the time comes. Thank you Mike.!
I would like to say thanks to Josh…. He really made sure that the car that I was purchasing was in great condition, and he took the time out to send me pictures of the car and every detail. Doing the whole process he kept me informed with everything and was very kind and eager to make sure my purchase went smoothly. So thanks Josh for the text message and phone calls.
It was a great experience in car shopping. I gave Josh a time limit and he went above and beyond in the time limit. Alex is a great Financial Planner.
Great service Lupe Chapa in service is so understanding and very professional!!
Great service that was on time and completely accurate. Really like the people !!
Mike was very knowledgeable and upfront. He certainly cared about us as his customer. We felt that he really enjoyed what he does!
I needed the oil changed and the tires rotated on my 2019 Canyon. I made the appointment on-line. The Dealership was ready for my vehicle when I arrived.
Great experience selling our truck to Fox Valley Buick! Rudy was easy to work with, professional, made us feel at ease and the process was quick and easy! Not exactly what we expected but we’re super grateful for Rudy and making our experience at this dealership exceptional! We’ll be back! Highly recommend this dealership and Rudy specifically!
Had to take my vehicle in today for some issues and a recall. Waited for a little but and then they realized I was waiting and offered a loaner vehicle. Love the great customer service there!
All dealerships should be as honest and respectful as Fox Valley Buick Gmc. Rudy was outstanding. I saw specials and promotions on their website. Much to my surprise, these were offered upfront without even bringing them up. No smoke and mirrors or bait and switch. $3500 off means $3500 off. My trade was promptly evaluated, and a fair price was quickly agreed upon. This complete experience was enjoyable, I have never felt appreciated buying a car like yesterday. I highly recommend Rudy and this dealership to everyone looking to buy a beautiful Buick or a killer GMC truck. These guys have nailed it and deserve the positive post above. Mike. St Charles.
Scheduled an oil change along with a few other small items. Lupe was very friendly and kept me updated. Will be returning for future service needs.
In and out in about an hour. No issues.
Good GMC dealer. Easy process and clean facility. Rudy and Alex made it very comfortable and never felt pressure.
I Would highly recommend this place for buying a car, very honest and reasonable people to do business with. Jim was the best sales associate you could ask for.
Purchasing a used vehicle at Fox Valley Buick GMC was one of the best car buying experience I have had. Working with Mike Hampel was a no hassle, no pressure process, especially as we came in just to look around. The lot was not full of rows and rows of cars which made the environment quaint but the selection was top notch and prices much more competitive than most dealers (even those so called discount dealers). This was a great experience for my son who was purchasing his first vehicle all the way through for purchase process. We have the utmost respect for their approach and would definitely pursue purchasing another car from them in the future.
