I read somewhere this car has a unique floor pan, which is odd because car companies moan at length at the cost of developing them, and then Fiat goes for a niche market with a unique offering.
Probably a stretched Tipo (someone designing the coupe took the wrong medicine).
Cheers for the replies, why I'm asking is that sometimes components can be cheaper if sourced from a more commonly produced car if the Mulipla shared the pan with another make.
