Five English guys are in an Audi Quattro, and are trying to get through to Ireland on the ferry.

An Irishman at the dock stops them and says "Oi" you can't come through here with five people in a Quattro.
Quattro means four and you're five!"

The driver says "Don't be stupid, Quattro refers to the drive train; it's a four wheel drive hence Quattro"

"I'm sorry" says paddy, "Quattro is four, and you can't come here with five people!!"

"Bugger that, where's your manager?" says the driver.

"He's busy! He is trying to sort out a couple in a Fiat Uno!!"
