The 1965-66 Shelby Mustang GT350, affectionately known as the Cobra, was a beast on wheels with only 562 units in ’65 and 1,378 in ’66. Its 289 cu in engine roared with 306 hp, making it more “zoom-zoom” than “comfort-cruise.” With quirks like a trunk-mounted battery that caused fume complaints and a spare tire cozily sitting where the back seat should be, these models were the epitome of “race first, comfort later.” And let’s not forget Hertz’s “rent-a-racer” GT350-H models—return them with fewer parts, anyone?
