Chevrolet Impala SS, the epitome of performance from 1961 to 1969, started as a humble trim option but evolved into a symbol of Chevy’s prowess. With engines ranging from a modest 250 cu in six-cylinder to a mighty 409 cu in V8, it offered muscle enthusiasts a buffet of horsepower. The 1965 model even ditched “idiot lights” for full instrument clusters, proving it’s smarter than your average car! By 1966, Chevy added side chrome trim to combat “door dings,” because who needs battle scars, right?
