The Ford's 021c Concept Car was unveiled ten years ago! When the car was unveiled, consumers werenĄ¯t ready for this concept, it was almost universally despised. But back to now, I'm sure you will like it. It's built from carbon fibre, it has some interesting features like the rear doors are hinged at the back that four wide opening doors for easy entrance and egress. The trunk functioned as a pull out drawer instead of a lift up lid.
