No No No No No No No No! Leave the black bits as they are. Colour coding it looks rubbish. The 100hp is perfect as it is. What you are suggesting is a no no.
No no no, it has the look of a Picanto! The black trim really sets off the lighter colours and gives it a bit of early eighties retro-cool (RS1600i anyone?). And it's not often the words 'eighties' and 'cool' can not be used in the same sentence. Still, each to their own; there are no 100HP Style Enforcement Agents here...
on the Fiat website they have those bits coloured on the configurator, I wonder if they are going to do it? TBH, it looks good on the grey cars and blue, but I like the black bits with white and red cars.
