As its name suggests, the 2007 Hummer H3 Luxury, which starts at $33,225, offers standard amenities not found on its lesser siblings. Among them are heated, power-adjustable front seats; leather upholstery; a Monsoon sound system including a subwoofer; and a leather-wrapped steering wheel. Options mirror those of the H3 Base and Adventure, with the exception of the Off-Road Suspension Package that carries a price of $1,375. Essentially, this adds components that are standard on the Adventure trim, including the rear locking differential and beefed-up suspension.
