Four-wheel drive is what distinguishes the 2007 Nissan Titan Crew Cab SE 4X4 from the two-wheel drive SE.  This full-size, five-passenger pickup hauls 9400 pounds and performs well on tough roads or nasty weather.  It is also a step above the base, which means it has a lot more convenience features.  Power comes from a 317-hp, 5.6 V8 engine and 5-speed automatic.  Along with all-wheel drive and electronic high-low gearing comes ABS brakes, a tire monitor, dual front and side airbags, and traction control.  Skid plates are also standard.
The SE 4X4 is exactly like the 4X2 in terms of features.  A security system, intermittent wipers, cruise control (with controls on the steering wheel), power mirrors, locks, and windows, MP3 compatibility, an overhead console, remote locks, front and rear cupholders, cargo tie-downs and towing wiring, and comfortable front row captain's chairs are all standard.  A chrome grille and bumper and leather interior trim gives the pickup a bit of class.  Various packages add more power features, an optional front bench seat (for three), a DVD player and audio controls in the back, an off-road package with stronger shocks and performance tires, and a Utili-Track and bedliner for the cargo bed.
