Howdy Folks,
Whilst going through my library of auto design books, I cam across this series of images; It shows a concept sketch, and two prototypes. It's interesting to see how the design progressed from sketch to near-final product. Note the front spoiler design they were playing with on the driver's side of the bottom car. Also notice the round fuel filler door on the bottom image... I don't think I've ever seen that before.
Enjoy!3DMCImages.jpg
