Made in Italy, and designed to drive 5 people over rough Roman roads without a problem. Front wheel drive and only made with Manual transmission.

Look its a fiat uno. I would be so cool if i had one.

Nigel Uno 

Often used to describe a UM troll that continues to bait posters with personal attacks because of his intense fear of anti-UM threads.

Often turns sports discussion into personal attacks in his desperate attempt to top the king and be "Uno"

Driven by a deep insecurity to be "Uno" because he suffers with a small penis, a pot belly, and mustard on his T-shirt, and with hope that Rich Rod that was a temporary nightmare, he continues on with his quest.

1) Himself

2) Poster--"What do you think of the Pryor and UM mess?"

Nigel Uno---"Uh, ah, um...you are Opti aren't you??"
