23. 1998 Fiat Multipla
Fiat has long used the Multipla name for its vans and mini-buses, dating back to the 1950s. The 1998 addition to the family was supposed to be the heir to a storied legacy, but instead became the punchline in more jokes than any American minivan design. There’s not way to say it politely: this thing looks bizarre. The front end appears to have been assembled out of leftovers from various model kits, the wheels are too small, and the back end could double as a greenhouse. Whether it was ahead of its time or just went too far is immaterial: the end result is that this Multipla divided by zero.
