The Geneva Motor Show is in full swing and automakers from all over the world are competing to see which one will present the most interesting vehicle. For example, Fiat introduced a concept car that is modular, allowing the customer to "choose" every part of the car they want.oneis called The Centoventi. Of course, it is an electric car and the customer himself chooses their number, or capacity. In addition, he can choose the complete interior and exterior, including the type of roof or bumpers, at his discretion. There will be many options and the owner will be able to drive a completely unique car.
