Update – Service Completed on 2/11/26 I wanted to
Update – Service Completed on 2/11/26 I wanted to provide an update following my recent service appointment. I scheduled a transmission drain-and-fill for my 2018 Pacifica Hybrid on very short notice and arrived on 2/11/26 at 8:55 AM. The service was completed promptly by 10:30 AM—about 1 hour and 35 minutes. The invoice initially showed $440+, but the advertised $179.95 special was applied, resulting in a final charge of $179.95 plus tax (~$197 total). During the appointment, I explained that I was doing preventive maintenance at relatively low mileage (35k) to ensure the transmission lasts after warranty expiration. I greatly appreciate that Service Director Kevin Tranter and the dealership went the extra mile to honor the advertised price and make me feel valued as a customer. The service advisor, Lillian, also acknowledged that the 2018 Pacifica Hybrid does not require removing the transmission pan and that the filter is not replaceable unless the transmission is removed—correcting the prior misunderstanding that led to inflated initial pricing. While my original concerns about advertising inconsistencies and staff familiarity with model-specific procedures remain valid, I want other customers to know that the dealership truly made an effort to rectify the situation. I would certainly return for future advertised promotions, knowing they will honor the price and provide proper service. Based on this resolution, I am updating my review rating from 1 star to 3–4 stars.
Reliable and feel very safe.
Love this vehicle. I feel safe transporting my grand daughters. It is reliable. It?s great on highway and city driving. I would recommend a GMC

Thank you Southtowne Mitsubishi for making my new car
Thank you Southtowne Mitsubishi for making my new car purchase simple and easy! Everyone was fun to work with! Will definitely come back! Really enjoying my new Outlander Sport!
Nicest truck I’ve ever owned
Got the Duramax Sierra SLT crew cab with pretty much all the options, I’ve tried other trucks and currently have a 2007 Chevy Duramax and it turned me to GM from the ford and dodge diesels I’ve driven/owned in the past. Blows my mind with all the options, super comfortable and rides quite nice for a truck.

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles
Good truck
Good tow truck and good ride for a vehicle. My wife enjoys the extra room in the full size back seat. This is my third GMC vehicle and I am not sure that I wouldn't own any other vehicle.

Great customer service from the Willmar Schwieters team! Even after sale they ensure things are going good with your new vehicle. They have a truly extensive and great looking selection of both new and used vehicles, and they ensure your trade in fetches as much as possible if you go that route. Sales person and sales manager both friendly and extremely knowledgeable, and I absolutely recommend this great service to anyone.
