2007 Jeep Wrangler Unlimited Sahara Package $16,990

The basic Wrangler X is quite spartan, though a CD player with an auxiliary input jack is standard. An optional "C" Package adds air-conditioning, upgraded cloth seats and a full-length center console. The "S" Package has those features, plus 16-inch alloy wheels, tow hooks, cruise control and a compass/temperature display. Also optional is a modular three-piece hard top (Freedom top), a sunroof-equipped soft top, a limited-slip rear differential, power windows, keyless entry, an Infinity audio system, a six-disc CD/MP3 player and satellite radio. The Jeep Wrangler Sahara is more upscale. In addition to having many of the Wrangler X's optional features as standard, it also features 17-inch alloy wheels, body-color fenders, a heavy-duty suspension and upgraded seat fabric. Options for the Sahara include 18-inch alloy wheels and a navigation system featuring "bread crumb" off-highway tracking. A 20-Gigabyte hard drive can also be added to the system to store music and pictures. Lastly, there's the trail-busting Wrangler Rubicon. This model is equipped similarly to the Sahara but features special drivetrain upgrades, an electronically disconnecting stabilizer bar and special BFGoodrich off-road tires.
