For decades, GMC was all about trucks and SUVs. But the recent popularity of car-based crossovers has cued yet another evolution, as GMC has moved into this market as well. The latest entry is the GMC Terrain. A small crossover, the Terrain stands out thanks to its stylish cabin, versatile backseat, ample standard features and sophisticated driving manners. Along with its mechanically identical sibling, the Chevrolet Equinox, the Terrain is a smart choice for a new or used crossover.
