The Unlimited is a version of the Wrangler chassis from 2004-2006, it was the longer wheelbase Jeep, and known as the TJL. For the 2007 year, the Wrangler was all new with the Unlimited being the 4 door version, and it is known as the JKL. The meaning has to do with the Go Anywhere nature of Jeep vehicles.
