📚 Vehicle History

Jeep Heritage:

Jeep, a division of Chrysler (now Stellantis), is renowned for its rugged, off-road capable vehicles with a history dating back to World War II.

Liberty Kj Introduction:

The Jeep Liberty (KJ) was introduced for the 2002 model year as a replacement for the Jeep Cherokee (XJ) in North America. It was positioned as a more compact and car-like SUV compared to the Grand Cherokee but retained Jeep's signature off-road capabilities.

Kj Facelift:

The KJ received a significant facelift for the 2005 model year, featuring revised exterior styling (front and rear fascias, fenders), updated interior appointments, and the introduction of the 2.8L CRD diesel engine to the US market. The 2006-2007 models represent the post-facelift iteration.
