New and used 2025 Buick Encore GX Avenir for sale near Des Plaines, IL

I was very fortunate to have the greatest salesman, manger, General manager and finance director in the business assist in my purchase. Thank you "Coach" for all you do for me and the family

The only reason I gave the interior a 4 is for the icons on the informations screen for Music, information and home, etc. are very dim and hard to see, especially during the day. After a while you know where they are and can just touch the area to get to what you want.

Worked with Brian again and had a smooth and great experience. I highly recommend this dealership and Brian.

Being 65...using the Mybuick App to use the phone is way more challenging than I would like!! I'm not tech savvy and STILL can't figure how to get my phone calls to be heard in the cars audio! I think it's a "me problem" but wish it was as simple as linking the Android app and Mybuick app.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

ENCORE IS THE PERFECT SIZE, YOU DON'T SIT REAL LOW AND IT'S NOT SO HIGH YOU NEED A STEP STOOL TO GET INTO IT WHICH IS WHAT I LOVE THE MOST ABOUT THE ENCORE!!

I was truly steered by God to this dealership. I am now a customer for life. I found them while searching for a new Hummer ev on the GMC corporate website. I can with great confidence declare that Marquardt GMC and their entire team are truly the pinnacle of what they advertise “Expect, honesty, integrity and transparency.” Frankly, in their quest for professionalism and value for the customer they exceed all expectations. I say this after a lifetime of experience in buying cars as I approach age 70. Please know it’s a smaller, family run type businesses. Note that is has successfully been in business since 1950. That is a testament that they are truly best in class at all that they do. The buying process always seem long, but they go through the effort to make you feel at home, address every concern with care and consideration and make the process comfortable and enjoyable in contrast to the adversarial approach others often take. My wife and I genuinely appreciate the blessings to have found this place, the people, and so happy with our new GMC Hummer Pickup. I can’t speak highly enough about Dave (Sales Mgr) and Tim M, Sales Associate. Thank you very much for the experience, the vehicle and all of the continued support.
