Inventive sales pitch - GroovyMucker
My sister went to a Hyundai garage to look at a Tucson which had been advertised as a 4x4 but was in fact FWD.

The salesman admitted the error, saying it wasn't actually a four-by-four but a "two-by-two".

Inventive, and also wrong.
It's a 4x2, unless it's had two wheels removed.
