This is my initial design concept (X1) for the Factory Five 818 WRX kit sports car design concept. It consists of a single, central tub design with different front, rear, and hardtop shells that can be used to vary the appearance.
It's nicknamed the "V.I.X.E.N." which (kinda) stands for:
Versatile
Interchangeable
eXoskeletal
