New and used 2026 GMC Sierra 2500 trucks for sale near Weyauwega, WI

West Side GM is genuinely committed to providing the best customer service! We purchased a used Malibu and the entire process was smooth from meeting with Jeff Maldwin to the finance manager. Jeff was very friendly, knowledgeable and walked through all of the details of the car, while being respectful of our time. I highly recommend this dealership for purchasing your next vehicle!

Kim was a very good person to work with & very friendly & knowledgeable.

I bought a vehicle a few years back from Julia and I wanted to take a moment to share how amazing Julia and her team are. They treated me like I was the only customer theret and were professional and attentive. I still have my car and love it. I would go back to Julia to buy a car again and I live in ILLINOIS!!

I had new tires put on my Chevy Malibu and the entire service team was friendly and professional. They were upfront about the timeline and had an area which allowed me to work. Highly recommend!

Talk to Charles he’ll make your buying experience the best you’ve ever had! We never expected to end up in Berlin but so glad we did!

My family has bought 22 cars and trucks from WESTSIDE GM and Diane Grant-Simenson over the last 30 years. Kudos to DIANE for her 30 years of selling our family so many vehicles!

Today, April 19th, 2023, I took both of our family cars to Bergstrom Auto-Oshkosh on Washburn. First vehicle a 2020 Chey Equinox and second vehicle a 2007 Toyota Camry. I'd like to compliment Jacob Durant who worked with me on the Equinox oil change, etc. Second individual for '07 Camry was Partrick Fitzsimmons. Both servce consultants outstanding!!! Very polite, pleasant, helpful, courteous, friendly, listened, advised, suggested what is needed, required, best for vehicle perfomances. I admire and respect their decency, honesty, caring attitudes. Thank You, gentlemen and Bergstrom!!

I?m an extremely busy person in medicine . I came in with limited time and sleep. My dealer , Larry R was phenomenal. He had all ready with the parameters I gave. I was in and out in no time and left the same day with a new vehicle 2025 Chevy Trax.

My car started making a noise, and I was planning on taking it out of town. I took it to the Service Department before leaving and worked with Brian. Brian was a true gentleman and simply AMAZING! He listened to my concerns and made sure the issue was fixed. I am so blessed to have worked with Brian. Thank you, Brian!

Kara Homan is a great sales person! She makes everything so easy to buy. She has a lot of knowledge about the vehicle's I'm interested in.

Easy and smooth going to a salesman that knows you and what you want and like. It makes the process so much easier. Will always go to him.

Their saleman got back to me promptly and offered follow up which was great . Not pushy though

The sales person Kim had excellent knowledge of the vehicle I was buying. I also liked the design and look of the 2025 Denali Canyon So far like the truck but still getting sed the all the controls.

I showed up without an appointment because I was in the area. Asked the young man at the entrance to the oil change building if they had any room to fit me in so I could have my transmission flushed with filter change (as recommended in manual due to the new style transmissions being a ?sealed? unit) as well as an oil change. He got me in later in the afternoon. I was in the waiting area only an hour for everything to be done. Pop and coffee available at no charge. Comfortable seating as well as a television. Very relaxing really.

Erik was awesome through the whole buying process! He was very responsive and understood what i was looking for. I am very happy with my new vehicle!
