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!

This is the second vehicle we have purchased from Royal
This is the second vehicle we have purchased from Royal Moore GMC, and once again it was the easiest car-buying experience we?ve ever had. From start to finish, the sales process was seamless, straightforward, and completely stress-free. We knew exactly what we were looking for, and there was absolutely no unnecessary pressure or back-and-forth?just clear communication and efficiency. They were incredibly accommodating with our timing and the speed of delivery. Omid oversaw the deal while Jeremy handled the sales side, and they worked in parallel to make sure our time at the dealership was kept to a minimum. Nathan in finance had everything prepared ahead of time, so the finance process was quick, smooth, and painless.

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 husband and I live in the Cincinnati area and found a new 2025 Yukon Elevation at Ron Marhofer for a great price. The price was as advertised online- no bait and switch with employee pricing or discounts that only certain groups qualify for- just a flat dealer discount. We worked with Steven and the process was smooth and easy- definitely worth driving 3.5 hours.
