A midsize SUV, the 2007 Nissan Pathfinder is available in four trim levels: S, SE, SE Off-Road and LE. The S, SE and LE are available with either two- or four-wheel drive, while the SE Off-Road is available as a 4×4 only. The base S offers amenities like 16-inch alloy wheels, power accessories, keyless entry, a CD stereo and cloth seating for seven. The Pathfinder SE adds wider tires, a roof rack with cross bars and a center pull-down armrest in the backseat, in addition to a longer options list. The SE Off-Road trim comes standard with heavy-duty Rancho shocks, underbody skid plates and additional electronic systems to improve off-road performance. The top-of-the-line Pathfinder LE is upgraded with upscale amenities like 17-inch wheels, a sunroof, heated leather seating and a Bose audio system. Optional items include satellite radio, a navigation system and a DVD entertainment system.
