Roberson Motors has a wide selection of new and used vehicles at our Portland, Oregon area dealership, including the legendary Jeep Grand Cherokee. The Jeep Grand Cherokee is known for its indomitable off-road capability and a wealth of customization options. Overcome the roughest terrain with your choice of a 3.6L V6 engine, a 5.7L Hemi V8 engine, or a 3.0L turbo-diesel engine, or upgrade to the SRT model with a 6.4L Hemi V8 engine for the most power. With further customization, you can turn your Jeep Grand Cherokee into an off-road force with a 4X4 Quadra-Lift air suspension system and elevated height setting. Or, your Jeep Grand Cherokee can take the form of a city cruiser with options for luxury seating features and family-friendly entertainment and safety systems.
