About Us

Some dealerships talk about being part of the community. At Auffenberg Buick GMC, that is simply the truth. We have been selling and servicing vehicles in Farmington since 1942, and our roots here run deep. If you are thinking about doing business with us and want to know who you are actually dealing with, this page is for you.

Over 80 Years of Serving Farmington and the Surrounding Area

A lot changes over eight decades. Vehicles have changed. Technology has changed. What has not changed is our commitment to the people who walk through our doors. We have sold vehicles to parents and grandparents who now send their own kids to us. Customers from Park Hills, Bonne Terre, and all across Jefferson County have been making the drive to Farmington for generations because they know what to expect from our team. That kind of loyalty means everything to us, and we do not take it lightly.

We Know This Is a Big Purchase

For most people, a vehicle is the second-largest purchase they will ever make. Only buying a home costs more. We never lose sight of that. Every customer who walks in deserves honest answers, clear information, and a team that actually listens. We are not here to push you toward something that does not fit your life. Our job is to help you make a decision you will feel good about for years. That starts with meeting our staff and building a little trust before anything else happens.

Transparency Is Not a Buzzword Here

We believe you should know exactly what you are getting before you sign anything. That means straight talk on pricing, honest conversations about trade-in value, and no runaround on financing. You can get an estimate on your trade from home before you even visit us. Our finance center works with all customers regardless of credit history, and we are happy to walk through every line of a deal until you are comfortable. That is just how we operate.

New Buick and GMC Vehicles, Plus a Strong Pre-Owned Selection

We carry a full lineup of 2026 Buick and GMC models, from the efficient Buick Envista to the full-size muscle of the GMC Yukon XL and the hard-working GMC Sierra HD. Our pre-owned inventory gives buyers more flexibility on price without sacrificing quality. We stock vehicles at a range of price points, including options priced under $20,000 for shoppers working with a tighter budget.

Service You Can Count On After the Sale

We want to be your dealership long after the paperwork is done. Our service center is staffed by certified technicians who know Buick and GMC vehicles inside and out. Routine maintenance, warranty repairs, and everything in between gets handled the right way the first time. You can schedule a service appointment online whenever it is convenient, and we keep current service and parts specials running to help you save on the care your vehicle needs.

Come See Us

We would rather show you who we are than just tell you. Stop by our Farmington location, browse the lot, and talk to one of our team members. No pressure, no script. If you have questions before you visit, our contact page makes it easy to reach us directly. We look forward to earning your trust the same way we have earned it from three generations of families across Farmington, Park Hills, and Bonne Terre.
