When I first set out to write this article, I thought, "Pfft. Piece of cake. Cars have changed so much, any brand that was around half a century ago is going to look unrecognizable today." Case in point, these six cars have changed wildly over the years.
At the same time, though, cars and brands have their own identities, a DNA that's all their own. Compare these cars with their modern versions, and at first, they might look about as related as Arnold Schwarzenegger and Danny DeVito. But look closer at the DNA clues in the lines, and they'll start to look a bit more like Kirk and Michael Douglas.
