"Popular Science" magazine road test comparison of three 1966 sporty fastbacks (Ford Mustang, Plymouth Valiant, and AMC Marlin) highlighted the Marlin's quiet interior, high quality upholstery and positioned seats with adjustable backrests that "permit almost any driver to find an ideal seat-to-wheel-to-pedal relationship", as well as the "best-balanced ride on good roads and bad". The two-barrel V8 engine with the three-speed automatic achieved 0 to 60 mph in 11.7 seconds, and was the quietest, but least responsive of the group. The test Marlin's standard drum brakes were criticized as inadequate, with the authors recommending the optional disk brakes.
