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!

It was by far the best experience of purchasing an automobile I’ve ever had. Very courteous and helpful. I actually went to GMC dealers in Va. and NC and they couldn’t help me get the SUV I wanted. Went to Cars.com and submitted 3 notice of interest to 3 different dealers and Zeigler responded within 5 minutes. No haggling and gave me a more than fair quote. Everything went smooth and finally heard from other dealers an hour or two later. Really appreciate the professionalism. Love my truck and it was delivered today! Thank you for all your help.

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.

Working with Drew at Briggs Nissan of Manhattan made the car-buying process remarkably smooth and stress-free. From our initial interaction, it was clear that this dealership operates differently—prioritizing genuine relationships over high-pressure sales tactics. Drew took the time to understand our needs and guide us toward the right vehicle, without ever making us feel rushed or pressured. In the end, we felt confident that we reached a fair and mutually beneficial agreement. Gabe in the finance department further reinforced the dealership’s commitment to a seamless experience, handling everything efficiently and transparently. If you’re looking for a dealership that values trust, respect, and long-term relationships, I highly recommend connecting with Drew at Briggs Nissan.

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.
