There’s a new standard on the Jeep Grand Cherokee Limited and Overland (optional on the Laredo), and it will have you pressing a key fob button again and again. This reviewer discovered remote start quite by accident. Upon reaching the parked SUV and finding the engine running and no one at the wheel, the situation was puzzling. At a much later point in time, the answer was found on the key fob where the lower right button (with two quick touches) locks the doors and starts the engine. On cold weather days, this is an especially nice feature. There are many other new treats on the 2007 Jeep Grand Cherokee, including a rear back-up camera (with live image shown on navigation screen), standard side curtain airbags as well as five new exterior colors. The Grand Cherokee with 5.7-liter Hemi V8 proves to be a monster of power, but the 2007 model year adds a 3.0-liter diesel to the gallop choices – making this full-size Jeep the first to offer a diesel engine. And, there’s a flexible-fuel E85/ethanol compatible 4.7-liter V8 engine. The test driven Jeep Grand Cherokee Limited 4x4 was loaded with various optional fare – like a $1,200 rear seat video entertainment system. Yet even minus the options, the Grand Cherokee Limited has a lengthy list of standards, including speed control, and power adjustable pedals with memory. Per gallon mileage estimates for the Hemi-powered 4x4 are 14 city and 19 highway. MSRP of the Grand Cherokee Limited 4x4 is $37,770.
