The Hummer H3 enjoys a cult following due to hearty four wheel drive components, substantial ground clearance and a cabin that balances the appearance of a rocky mountain climber with warmth in its seats and navigation to allow driving down a rugged trail or to its owners every day to their job without being thrown out of the car. H3 construction is light but strong, steering is accurate, and safety ratings are solid, which makes this SUV a versatile adventure companion of young adventurers.
