From the work-ready GMC Sierra 1500 to the refined, three-row Buick Enclave, we carry models purpose-built for Missouri life — whether that means hauling a boat to Wentzville, running carpools through O'Fallon, or making the daily commute into St. Louis as comfortable as possible. Visit us at our St. Peters showroom and we'll help you find exactly the right fit.
GMC Trucks Built for Serious Towing and Capability
GMC has long been the choice for buyers who need real, proven capability — and our truck lineup delivers on that promise with every model year. Whether you need a full-size workhorse, maximum heavy-duty towing, or a midsize option that's easier to maneuver around town, we have it on our lot in St. Peters.
GMC Sierra 1500
A full-size truck that sets the standard for refinement and capability. The Sierra 1500 offers class-leading towing and payload, the innovative MultiPro tailgate, available Super Cruise hands-free driver assistance, and a premium interior across Denali and AT4 trims that rivals luxury vehicles.
GMC Sierra HD (2500/3500)
When the job demands maximum towing capability, the Sierra Heavy Duty delivers without compromise. With available gooseneck and fifth-wheel towing configurations, this is the truck Missouri contractors, farmers, and serious haulers count on day in and day out.
GMC Canyon
The midsize option that proves you don't have to sacrifice capability for maneuverability. The Canyon punches well above its size class with impressive towing capability and is available in capable AT4 off-road and refined Denali trims — ideal for buyers who want truck utility in a more accessible package.

Buick SUVs: Refined Luxury With Family-Forward Features
Buick occupies a unique position in the market: genuine luxury refinement — quiet cabins, premium materials, advanced safety technology — delivered in approachable, family-sized SUV packages. For buyers in the St. Louis area who want more than a mainstream SUV without the price tag of a European import, Buick is often the smartest answer.
Buick Enclave
The flagship three-row luxury SUV with seating for up to seven. The Enclave's QuietTuning technology makes the cabin remarkably serene, and its advanced safety suite and beautifully crafted interior make every drive feel premium — whether you're heading across St. Charles County or across the country.
Buick Envision
A midsize luxury SUV that delivers a refined ride, premium materials, and advanced driver assistance features — without the bulk of a three-row. A smart choice for couples and smaller families who want genuine luxury in a more manageable size.
Buick Encore GX
A sporty compact crossover with available AWD, intuitive technology, and Buick's signature premium touches — perfect for smaller families or as a highly capable second vehicle. Easy to park, easy to drive, and loaded with the features that matter.
