Welcome to Guaranty Chevrolet Pontiac & GM Certified


Hi, I'm Shannon Nill the dealer here at Guaranty Chevrolet Pontiac and GM Certified. Guaranty is located in Junction City, Oregon. A delightful Scandinavian town in the Southern Willamette Valley, just five minutes north of the Eugene Airport.

Our dealership is out of the big city, so our taxes are less, our insurance is less, our sales expense is less, and therefore our cost of doing business is a whole lot less! Our high volume and low overhead saves YOU money. That's why we say, "Eggs are cheaper in the country, and so are new and used cars and trucks".

Whether you are ready to buy or simply doing research for a future purchase our website and sales team are here to assist you! Search our inventory for new Chevrolet Avalanche, Aveo, Cobalt, Colorado, Corvette, Equinox, Express, HHR, Impala, Laredo, Silverado, Suburban, Tahoe, Trailblazer or Uplander models.

We also carry the Pontiac line of G5, G6, Grand Am, Grand Prix, Montana, Solstice, Torrent and Vibe models.

Guaranty has one of the largest selections of quality preowned trucks in the Northwest. Often we carry full size Chevrolet, Dodge, Ford and Toyota trucks.
