The iconic Wrangler looks little different at first glance, but the latest generation features a number of important improvements. Jeep has increased the wheelbase and length for some badly needed extra interior room. A 3.6L V-6 is the standard engine. The model lineup includes the Wrangler Sport, Sahara, and Rubicon. Serious rock hoppers should get the Wrangler Unlimited Rubicon, which has locking differentials, Active Sway Bar System, and dedicated off-road tires. One often overlooked fact about the Wrangler is that it is one of the least expensive convertibles on the market. Most models include the manual soft top, but the 3-piece hardtop is available for less than $1000.
