The 2027 lineup at Sapaugh Buick GMC covers a surprisingly broad range of needs. There’s a compact SUV for everyday errands, two three-row SUVs for growing passenger lists, and two full-size choices for families who consider “packing lightly” an unreasonable request.

Our current 2027 inventory includes the GMC Terrain, Acadia, Yukon, and Yukon XL, along with the Buick Enclave. Shoppers searching for 2027 new vehicles for sale or lease in Herculaneum can compare them all here, just a short drive from Festus, Crystal City, Arnold, and the rest of Jefferson County.

The five-passenger 2027 GMC Terrain brings a manageable footprint, up to 63.5 cubic feet of cargo space, a 15-inch diagonal infotainment screen, and a long list of standard safety and driver-assistance features.

Elevation handles daily driving with plenty of comfort and convenience. AT4 adds a lifted ride height, all-terrain tires, and off-road-minded hardware, while Denali answers with premium materials and upscale tech. Our 2027 Terrain inventory has included Elevation, AT4, and Denali models, giving shoppers several ways to configure a 2027 GMC Terrain for sale or lease.

The 2027 GMC Acadia seats up to eight in Elevation form and offers up to 97.5 cubic feet of cargo room. Every trim uses a 2.5-liter turbocharged engine rated at 328 horsepower and 326 lb-ft of torque.

Elevation covers the family-hauling essentials, AT4 adds all-wheel drive and off-road-tuned capability, and Denali and Denali Ultimate turn toward premium materials and comfort. Our 2027 Acadia selection has included Elevation, AT4, and Denali Ultimate trims, giving families options ranging from practical to rather unapologetically pampered.

The 2027 GMC Yukon seats up to eight and comes standard with a 5.3-liter V8. Available powertrains include a 6.2-liter V8 and a 3.0-liter Duramax turbo-diesel, all paired with a 10-speed automatic transmission.

Trims range from trail-ready AT4 models to the luxury-focused Denali and Denali Ultimate. Our 2027 Yukon inventory has included Denali and Denali Ultimate models, a fine choice when the school run deserves a little more authority.

The 2027 Yukon XL stretches the Yukon formula for considerably more room behind the third row. It’s built for road trips toward the Lake of the Ozarks, airport pickups in St. Louis, and those weekends when half the garage somehow needs to come along.

Our 2027 Yukon XL selection has included Denali and AT4 Ultimate models. Available Super Cruise, adaptive air suspension, advanced trailering technology, and V8 or turbo-diesel power help the Yukon XL make long distances feel a lot shorter.

The 2027 Buick Enclave pairs three rows of seating with a quiet, refined cabin and up to 97.5 cubic feet of cargo space. Every trim is powered by a 2.5-liter turbocharged engine making 328 horsepower, and the dash is anchored by a 30-inch diagonal display.

Preferred, Sport Touring, and Avenir trims let you choose between well-equipped value, sportier styling, and Buick’s most luxurious appointments. Our 2027 Enclave inventory includes all three.

Whether you want a 2027 GMC Terrain for lease, an Acadia or Enclave for sale, or a new Yukon or Yukon XL with serious passenger and cargo capacity, Sapaugh Buick GMC can help you compare trims, drivetrains, features, and current availability.
