I had an amazing experience at Zeigler Buick GMC of Lincolnwood! From start to finish, everything was smooth, professional, and stress-free. Mariya was absolutely outstanding. She was knowledgeable, patient, and genuinely cared about helping me find the right vehicle. She took the time to answer all my questions and made sure I was comfortable every step of the way. I ended up purchasing a 2026 Buick Envista, and I love it! The car is stylish, smooth, and exactly what I was looking for. Mariya made the entire process enjoyable and easy. If you?re looking for great customer service and a team that truly takes care of you, I highly recommend Zeigler Buick GMC of Lincolnwood and definitely ask for Mariya!

David Scott Lee GMC is the best in the Biz. I have owned 6 GMC yukons over the past 20 years and the last 3 I have purchased from Scott Lee GMC. They have the highest level of customer service that I have ever experienced with any of the dealerships that I have worked with. They are my lifetime GMC dealership.

Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.

My business truck, in very cold weather, had a momentary maintenance code. While she was in for the code, I requested a service be done on the drive train, ie. tranx, diffs, and txfr case. Service representative Sonya got me in and out, back on my schedule, out of town, right on time. Her performance was exceptional, as was all of the aspects of my service with Laura GMC in Sullivan Mo!!!!
