We bought a $2,700 1989 Suzuki Carry kei truck and tried to conquer three of Colorado’s highest passes. With a 550cc engine, no first gear, and sheer stubbornness, we oil-change at the trailhead, pick our way up Cinnamon and Engineer—often in reverse—deal with overheating, ice, cliffs, and weather, and still tag two summits. Should you buy the cheapest kei truck and send it into the San Juans? Watch and decide.
