Most luxury SUVs have evolved into pampering on-road transport for their well-heeled buyers, backing away from off-road prowess and their truck-based roots. So does that make the Lexus GX a dinosaur? Not necessarily. Sure, nothing is "crossover" or "car-based" in this old-school vehicle. Consider the GX a Toyota 4Runner that was sent to finishing school, earning straight-A's when it was there.
