Not to knock anyone's choices, but this thread is about the best looking car of all time, not your personal favorite. for instance, I love the idea of the Skylines, but they are not a beautiful car. They are great, and look good, but I think you are confusing performance with looks.

Chosen for what it became, a an idea that anyone could afford a car, and the first cars to be hotrodded.
