Jeep faithful will be pleased that the Wrangler Unlimited embodies all the traditional Jeep attributes, adding much-needed cargo room and two more doors. The Wrangler Unlimited has a stiffer frame, longer 116-inch wheelbase, and retuned suspension, which should help tame the infamously jittery on-road ride. A 3.6L V-6 couples to a standard 6-speed manual or optional 5-speed automatic. Electronic Stability Program (ESP) is standard. 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.
