The results ranged from being simply forgettable (Zagato Monomille), ridiculously daft (Boneschi Doblone) or just plain ugly (Giannini Punto 4x4 TL), but one of the concepts stood out from the flock for being brilliantly bold. This was the Fiat Scia, presented to the public at the 1993 Turin Auto Show.
