Back in the day, the Jeep Wrangler was only for serious off-roaders. Posers might visit, but assaulted by the SUV’s sluggish acceleration, clumsy handling, rough noisy ride, and spartan hose-out interior they weren’t likely to stay long (or return after leaving). But Chrysler has worked steadily to eliminate these downsides and render the Wrangler fit for everyday use. Back in 2007 the Wrangler grew in size and became available in extended wheelbase four-door Unlimited form. Last year its interior was substantially upgraded. And this year the unloved 202-horsepower 3.8-liter “minivan” V6 has been replaced by a 285-horsepower DOHC 3.6-liter “Pentastar” V6. Meanwhile the chassis has been tweaked repeatedly to improve on-road ride and handling. So, with all of these improvements, is the 2012 Wrangler Unlimited as suitable as any other SUV for running the kids to school and then dropping by CostCo?
