Final Selection of Photographs for Short Assignment

I am happy with all the photographs that I have previously posted so I have decided to choose a theme for the photographs which will make it easier to select a final 10. After looking at my photographs I saw the same shape reappearing in a lot of the photographs, this shape is a circle. I'm not sure whether the car manufacturers purposely repeated the shape of the a circle throughout the vehicle or if it happened by accident, but I feel the circle represents one of the most important components of a car... the wheels. So I have decided my final selection should contain all of or part a circle in each photograph.
