Well, it's official--crossovers have crossed over and are now gaining a strong foothold on the SUV market. Take the all-new 2010 GMC Terrain five-seat crossover for example. This American-made marvel is roomy, has tons of standard features and gets an impressive 24-32 mpg on the highway. The Terrain is the twin of the Chevy Equinox and boasts a bold front grille and a sleek, modern interior, and was on full display at the 2009 LA Auto Show.
