19. Peugeot 504 Convertible
Peugeot was always less avant-garde than Citroen but more elegant than Renault and the 504 series proves it. They introduced it in 1968, and the 504 was a modern, advanced family sedan. However, the coupe/convertible version is the most popular for obvious reasons.
In those days, the Peugeot design team did the sedans and wagons. But they asked the Italian design house Pininfarina to style and produce a coupe/convertible combo. The result was one of the most elegant models of the ’70s and a classic of the French car industry. You could get the 2.0-liter four-cylinder engine. However, the best option was the 3.0-liter V6 with 170 HP with enough grunt to cruise down the French Riviera.
