The Wagoneer debuted in 1963 to replace the venerable Willys Station Wagon that had been manufactured since 1946. It originally sold in two and four door versions and as a panel truck. Although it went through several updates, the Wagoneer sustained through three corporate owners and several of their upheavals and was produced for twenty-nine years (1991).
It's interesting to note that although Jeeps had been made since 1941, the name was still in quotes nearly twenty years after the fact. From the start until this point, nothing was officially given the name Jeep. I suspect the change occured shortly after this point when the company changed their name from Willys Motors to Kaiser-Jeep.
