Never seen those concept drawings before. For those that don't know, what you're looking at is drawings of an AMC Matador sedan and wagon, based on their 'new' coupe body.... For whatever reason, AMC brought out an all new Matador in coupe form, while the sedan and wagon remained on the old platform. Maybe AMC just didn't have the development money by this time to do all 3 bodies at once. Anyway, the sedan and wagon bodies never did get to production......
Here is another AMC wagon that didn't make it. As a result, AMC experimentals soon became regular showtime fare. For example, 1967 saw an AMX III that previewed Javelin front-end styling as well as the general shape of the Hornet Sportabout wagon then four years away. And though we didn't know it at the time, 1968's AMX-GT was, for all intents and purposes, a preview (warning?) of the 1970 Hornet-based Gremlin. Though not part of Project IV, the bold AMX-GT suggested that the later Gremlin would have looked great with a Javelin instead of Hornet front end. Built on a 97-inch wheelbase, the AMX-GT bowed at the New York Auto Show in April 1968 wearing simple flush wheel covers and red paint with a white bodyside/roof stripe. It was later given five-spoke road wheels and black hood/roof paint. Rear side glass was fixed, but B-pillars were absent. ©2007 Publications International, Ltd. The 1968 AMC AMX III sportwagon concept car was basically a 1968 AMC Javelin coupe turned into a four-door. It didn't make it to showrooms. A final AMC concept car from this period was the 1967 AMX III "sportwagon." This was was also a virtually stock 1968 Javelin in front, but included a stretched four-door body with a fastback wagon tail. A November 1967 mockup suggested that AMC considered adding a four-door Javelin at some point. A pity the notion went no further.
