Lincoln's luxury pickup truck adds an extended-wheelbase model, optional navigation system, and revised styling for 2007. The Mark LT is essentially a dressed-up Ford F-150 SuperCrew crew cab. For '07, a 150.5-inch wheelbase model with a 6.5-foot cargo bed joins the 138.5-wheelbase/5.5-foot bed model. Both have two front buckets and a rear bench seat for five-passenger capacity. The lone powertrain is a 300-hp V8 and 4-speed automatic transmission. It comes with rear-wheel drive or with 4WD that should not be left engaged on dry pavement but includes low-range gearing. ABS is standard. Side airbags and curtain side airbags are not available. Leather upholstery is standard. A navigation system and 20-inch wheels are newly optional. Other options include power-adjustable pedals, sunroof, DVD entertainment, rear obstacle detection, running boards, and a tubular bed extender.
