Sport and Sahara models come with a much more powerful 4.0-liter six-cylinder engine. Sport ($19,155) includes an AM/FM stereo, too, along with a back seat and full carpeting. The top-of-the-line Sahara comes with more features, more style and adds more than $2,000 to the price of a Sport. You can also add significantly to the cost of the Sport by ordering a lot of options. You can see prices of some of them on the specifications page, but you'll have to do your homework at the dealership to obtain an accurate bottom line.
