In appearance, the Grand Cherokee is modern and square-edged, with a fashionably high waistline and small side windows. The shape of the body is designed to protect the sides of the vehicle from potential road debris. Revised taillights distinguish the '07; otherwise Grand Cherokee's outside appearance hasn't changed significantly since '05.

While conventional SUVs, such as the Dodge Durango, are built on a separate frame like a truck, the Grand Cherokee uses an unusual construction scheme Jeep calls Uniframe, a close marriage of a welded steel unit-body and underlying front and rear modules. This is an extremely sturdy and rigid concept developed back in Jeep's days with unit-body pioneer American Motors. The Grand Cherokee has earned a five-star safety rating in both front and side impact tests from the federal government.

New for 2007: The base-level Laredo model has been dressed up a bit. Door handles are now body-color (instead of black), and the black bodyside moldings have been redesigned.

Limited models still present a flashier appearance, with a chromed grille, bright inserts in the bumpers, and accent-color bodyside molding.

The Overland is distinguished by mesh-texture grille inserts between its traditional vertical grille bars, which are Platinum in finish; Platinum accents also appear on the bumpers, side molding, roof-rack side rails, liftgate light bar, and side-view mirrors. Wheels are chromed, and the front sill guards are now brushed stainless.

Jeep has reached deep into its heritage to revive the Overland name. First built in 1903, the Overland automobile was the earliest ancestor of the Willys. Willys played an instrumental role in the development and production of the World War II-era Jeep, but was also the first automaker to seriously envision a civilian market for a military-style utility vehicle. The Willys Jeep debuted in 1946 and had its name shortened to just-plain Jeep in the early 1960s. Although the Jeep brand has passed through several owners since then, its lineage remains unbroken.

The SRT8 has a monochrome look all its own, relieved by bright trim at the belt level and bodyside and accented by enormous five-spoke, 20-inch forged aluminum wheels. Functional air ducts in its more bluff front bumper fascia improve brake cooling. The rear bumper is cut out to accommodate dual four-inch exhaust tips, and the extended side sills are claimed to enhance downforce. SRT8 is available only in Bright Silver, Brilliant Black or Inferno Red. It looks hot, very sporty.
