If you're a fan of Carroll Shelby, particularly his Mustangs, then there's a lot to love among this group. One ad from July 1965 aimed to sell the GT350, but with an ocean of text and a tiny picture, it probably could've used a once-over by Don Draper's team. By December '65, the copywriters ironed out the problems with a spot proclaiming boldly "Shelby GT350 is 'Son of Cobra.'" The company offered some great accessories, too.
For those into European motoring, there's a humorous attempt to sell the Alfa Romeo Giulia as both a racecar and family hauler. Toyota also boasts about the winning record for the 2000GT. Among the best text comes from BMW for lines like: "What's BMW got? The most advanced high-performance engine in any production car, for a cruising speed of 100 mph." Of course, Volkswagen's famous "Lemon" ad for the Beetle also gets its due here.
Separately, each of these ads is fascinating, but taken together they tell the story of a great decade of motoring. Go give them all a read at Car and Driver.
