The 2006 Hummer H3 comes as one model ($29,500). Two major option packages are available that allow a buyer to focus on more luxury or on serious off-roading. The base price includes cloth-covered seating for five with manual lumbar adjustment for the front seats and a second-row seat that is split 60/40 and can be folded down to expand the cargo floor. Also standard are a tilt-adjustable steering column, power windows and locks, remote keyless entry, an audio system with a CD player, cruise control, air conditioning, an electronic rearview mirror with temperature and compass readings and a year's subscription of the OnStar telematics system. Also standard: 265/75R16 Goodyear all-terrain tires mounted on 16-inch wheels, a full-size spare tire, daytime running lights, fog lights. Safety features that come standard include antilock brakes (ABS), traction control, frontal and side-impact airbags (torso protection) for the driver and front-seat passenger, and a tire-pressure monitoring system. Side airbag curtains ($395) are optional and we recommend them for the head protection they can provide to you and your passengers in the event of a side impact or rollover. Leather seating with seat heaters and power adjustments for both front seats and a leather-wrapped steering wheel are included in the Luxury package ($3,125), which also includes a Monsoon audio system with an in-dash six-CD changer, upgraded sun visors with extenders and special floor mats. The Adventure package ($1,025) includes a rear-locking differential and high-ratio transfer case for enhanced off-road traction, unique 33-inch, 285/75 BFGoodrich off-road tires and special front and rear floor mats. The off-road suspension setup can be added to the Luxury package for $925.
