    The salesman was very helpful and patient through our decision process on choosing the right vehicle. The sales manager did an excellent job putting together a financial deal that met our needs. Overall, a great car buying experience.

    My husband and I went to pick up our 2013 GMC Terrian from being serviced at Courtesy Buick GMC in Crystal Lake, Il. We received the Devastating news of high repair cost with NO WARRANTY two-days before Christmas. My husband had previously spoken to David Schurch who appeared very positive and helpful. Due to the notice of concern and compassion of Rik Fregia, we were able to "Trade-In & Purchase" in a SMOOTH TRANSITION 2017 GMC Terrian! David Schurch and Rik Fregia went above and beyond to ensure that we received exceptional customer service. We will forever be customers and referrals all of our family and friends. Angela & Gregory S.

    I had a great experience purchasing my car at Courtesy Buick today. I had visited 4 Buick dealerships in the area and the level of customer service at Courtesy was above what I had experienced. I did a lot of research on the car I wanted and on my trade prior to starting the car buying process. I also visited and tried to negotiate at the 4 other Buick dealerships and could not get the deal I wanted. One car sales man at a different dealership told me it would be impossible to get the deal I wanted. Mike Bell was the specialist I worked with at Courtesy Buick and he was great. Mike truly championed for me to make ensured I purchased exactly what I wanted. Mike was very detailed. He gave me a tour of the facility, explained the processes, services and features that came along with purchasing my car. I walked out with the best deal and value that surpassed other dealerships in the area. I am extremely happy with the experience and purchase.
