You have some cool cars there!
When we were ther in January, I saw a lot of the "utes" and really liked the styling, I think they would go over pretty well over here.
The ones I liked were the Ford Falcon SX (I think?

)
and the Holden ute.
They were cool in that they were smaller than a regular truck here, but still had a cargo bed to haul stuff about in.
The holden ute that is in Oz had a counterpart here in the states for a while, called the El Camino, but it was discontinued quite a few years back.
If I can I will try to see if I can dig up a link to the ute pages.
I really liked ' em.
