Ultimately, and in line with Roy Abernethy's new marketing strategy, the decision was made to build the new fastback model on AMC's intermediate-sized Rambler Classic platform. The development team, under distinguished American designer Dick Teague, had to work with considerably smaller budgets than their counterparts at Detroit's Big Three to create the new Marlin. They created a large, roomy and luxurious fastback which incorporated a number of design features from the Tarpon show car. The signature roof line from the windshield with the Marlin's "skylight permits carrying through the true fastback line in an unbroken sweep." However, the roof was raised over the rear passenger area when Abernethy, who was six-foot-four (193 cm tall), insisted on being able to sit in the back seat of the design studies. Teague worked for Chrysler as a stylist during the mid-1950s and the fastback-styling of the lost 1956 Chrysler Norseman concept car's "resemblance to (that of) the 1965 Rambler Marlin fastback coupe, or vice versa, was (said to be) uncanny."
