What is a classic car? It seems like a simple question, but in reality, the definition is always changing. Back in the late '60s, first-generation Camaros and Firebirds were considered cool cars, but they were also rather commonplace. Now, those cars are highly prized and acknowledged by everyone as true classics. In the 1980s, the same could be said of second-gen Camaros—they weren't seen as classics then, but now they certainly are.

Mention the Chevy Nova today, and most people will envision a high-performance muscle car. However, the Nova's beginnings were much less glamorous than that—it started out as an optional trim level on the unassuming Chevy II commuter car. The Nova's image has changed so much, most people even forget the car wasn't offered with a V8 engine for the first two years of its production, even in its top-of-the-line Super Sport form. Back in '62, you got to choose between a 153ci four-cylinder or a 194ci inline-six—not particularly exciting.

As car enthusiasts, we tend to think of our vehicles as much more than a simple mode of transportation—to us, they're rolling works of art. However, it's also important to keep in mind that these timeless automotive creations are meant to be functional, not just sit collecting dust like pretentious sculptures. Every car or truck has a purpose, a role it was designed to fulfill. As for this 1961 Impala SS convertible, its purpose is clear: this car was built to cruise.
