21: Chevrolet Impala
Released in 1958, the Impala is one of the best-selling passenger cars of all time. The Impala nameplate has been in production for decades. Admittedly, the last two decades haven’t been the greatest for the brand. But there was a time when the Impala was the pinnacle of automotive design. The Impala has long been the face of the Chevrolet sedan lineup and there have been multiple incarnations of the model line (via Motor Cities).
In recent years, the 1995 Impala SS introduced a resurgence to the brand while the mid-2000s models were bland. The modern Impala has fallen out of favor as the crossover vehicle becomes the new normal. But looking back in history, the Impala was one of the most iconic and beautiful cars GM ever built.
