New Buick and GMC Vehicles at Bergey's Buick GMC

Welcome to the Bergey's Buick GMC showroom in Souderton, Pennsylvania - your local destination for two of the most respected names in the industry. Whether you're drawn to Buick's signature quiet luxury and refined SUV lineup or GMC's Professional Grade trucks and bold capability, our showroom has the right vehicle for your lifestyle. Bergey's has represented GMC since 1972 and Buick since 1998, bringing decades of brand knowledge and community commitment to every sale. As a 5th generation family-owned dealership group, we operate by the Golden Rule - treating every customer the way we want to be treated, with no pressure and no gimmicks from start to finish.

New Buick SUVs

Buick offers a refined, SUV-only lineup built around the idea that luxury and accessibility don't have to be mutually exclusive. The Envista is Buick's most approachable entry point - a sleek crossover with a distinctive coupe-inspired roofline and a comfortable, well-appointed cabin. The Encore GX steps up with a slightly larger footprint, available all-wheel drive, and the kind of premium interior refinement that sets Buick apart in the compact segment. For drivers who want a little more space without stepping into a full-size vehicle, the Envision delivers a near-perfect balance of size, efficiency, and technology in a beautifully appointed package. At the top of the lineup, the Enclave is Buick's flagship three-row SUV - a mid-size family hauler with seating for up to seven, available Super Cruise hands-free driving technology, and the premium Avenir trim for those who want the ultimate in Buick luxury. Every Buick model comes standard with Buick Driver Confidence, a comprehensive suite of advanced safety features, and QuietTuning technology for a composed, serene cabin experience.

New GMC Trucks

GMC has been synonymous with Professional Grade truck capability since Bergey's first took on the franchise in 1972, and today's lineup continues that tradition with more power, technology, and refinement than ever. The Canyon is GMC's mid-size pickup - available in off-road-ready AT4 and AT4X trims alongside work-focused configurations - making it a capable and manageable option for drivers who want truck capability without full-size bulk. The Sierra 1500 is GMC's full-size flagship, blending impressive towing and payload capacity with an elevated interior, available MultiPro tailgate, and top-tier Denali and AT4 trims that push the boundaries of what a truck can offer. When the job demands more, the Sierra HD 2500 and 3500 step up with serious heavy-duty capability - available in powerful V8 gas or Duramax turbo-diesel configurations - for drivers who need maximum towing and payload performance.

New GMC SUVs

GMC's SUV lineup brings the same Professional Grade DNA found in its trucks to a family of capable, refined utility vehicles. The Terrain is GMC's compact SUV - a sharp, feature-rich option with an elevated interior and available AT4 and Denali trims for drivers who want more personality in a right-sized package. The Acadia is a three-row mid-size SUV built for families, with seating for up to eight, a turbocharged engine delivering strong performance, and a premium Denali Ultimate trim that raises the luxury bar significantly. For those who need full-size space and capability, the Yukon and Yukon XL stand at the top of the GMC SUV hierarchy - offering powerful engine options including an available Duramax diesel, seating for up to nine, and the breadth of trim options from rugged AT4 to the feature-rich Denali Ultimate.

New GMC Electric Vehicles

GMC is redefining what electric capability looks like with a growing lineup of electric vehicles that deliver the same Professional Grade standard as their gas-powered counterparts. The Sierra EV brings full-size truck utility to the electric segment with impressive range, available AT4 and Denali trims, and Super Cruise hands-free driving technology. The Hummer EV and Hummer EV SUV make an entirely different kind of statement - combining massive electric output, available CrabWalk diagonal driving technology, and off-road capability that no other electric vehicle can match.
