When you know you've found a good thing, you hold on to it. This is the mindset that led Michael Argandona, of Huntington Beach, California, to keep this 1989 Pontiac Firebird Formula for three decades. He has lovingly maintained it, keeping its smooth black paint and sleek sheetmetal in immaculate condition. The result is a car that's just as cool today as it was back in '89.

Classic cars often become family heirlooms, passed from generation to generation over the course of decades. Not only does this process ensure a vehicle remains in good hands by keeping it in the family, it also maintains a strong sense of appreciation for these timeless cars and trucks. After all, it's one thing to see them in pictures and read about them in magazines, and entirely another to get your hands dirty under the hood and feel the exhilaration behind the wheel. This 1969 Camaro RS was recently restored in preparation to be handed down from a grandmother to her grandson.

As the years pass, many classic cars diverge from their stock form. Often this is due to the inevitable wear and tear on original components from driving or exposure to the elements. Instead of sourcing original-style reproduction parts, some owners will take their cars in a different direction and begin making modifications. While there's certainly nothing wrong with modding a car to make it your own, we also enjoy seeing classics restored to exactly as they looked when they rolled off the assembly line.

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.
