Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

Big thanks to our salesman Brian for excellent service. Very through and he,Paul in finding the right vehicle for us. Prompt courteous service. A very satisfied customer. Highly recommend Woody and ask for Brian.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Juan was excellent to work with, we quickly agreed on a price, the vehicle was cleaned and ready to go by the time the paperwork was complete. Highly recommend.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

We had the best experience at the Arnie Bauer dealership! As a first time car buyer, the process can be a little scary and overwhelming. However, Brandon and Alex were amazing. They walked me through every step and were beyond easy to work with. I could not imagine having gone somewhere else. Will definitely only be using them for car purchases in the future!

Needed key fobs replaced. They were ordered and came in within the next couple days. Scheduled the service appointment and all was completed within two days. Have received great service upon all my visits.

Nathan and Kevin was great. They made the car buying experience very simple and made sure that all of my questions were answered. Im very happy with my new Envista.

An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!

What a great experience at D? Arcy Buick Dealership in Joliet IL. The staff was friendly, honest, and made the whole process easy. Ray our salesperson went above and beyond. I love my new Envision Sport and would definitely recommend D?Arcy Buick and ask for Ray!!

Somehow the rear window wiper blade cover on my 2019 Buick Encore went missing.... Being a long-time friend and customer of Mike's, I went to his GMC service center for replacement, and was grateful that Bill Haggerty replaced the missing cover without charge! As always been my experience, GREAT service and GREAT dealership! ...Tom Noble

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!

Always a great and personalized experience! Definitely a VIP experience with every transition and handoff throughout the entire experience. Dominic and the rest of the team personalize the experience, and go above and beyond. The follow-up is next level between the technology and personalized touch. They have a loyal customer in our family!

I and my wife only use the dealer's services for maintenence and repairs. We are always satisfied with the quality of the repairs and the friendliness of the office technicians

Battery wasn?t installed correctly. I had returned my car to get the battery installation corrected and had to miss work. I was disappointed with the work.

Made a online appointment came in and they did a oil change and tire rotation. Happy with the service.

Ernie was a great salesman he walks you through eve step of the process

It was amazing. Efficient, pleasant, and quick. We love our new Buick. We usually do not look forward to the process of purchasing a car. It was actually enjoyable.

Mike Lorenzo, Kevin O Boyle D Arct Luke Stiller were the best people I?ve ever dealt with in a car dealership and I bought over 20 cars

The staff is very experience and professional. The estimate for repairs were in line with the services. I compliment the facilities with free coffee, water and soft drinks.
