Found this for sale on the Aussie ebay site. Maybe you guys have seen this before,I haven't. Kinda looks like an old Ford Country Squire wagon from the back and an early 70's Caprice from the front.

I've seen that type before. I have a book that is a compilation of auto mag reviews of the El Camino. Several of the articles are for the Aussie elky. They are small and a bit strange, but they were called an El Camino by GM/Holden.

and an early 70's Caprice from the front.
[/url] Looks more similar to a early to mid 70's LTD nose to me...just an observation.

Pretty much a standard Holden ute of the period. You should see the Holden One Tonner, which has the same cab and a flat bed body.

Those Aussie UTEs have been made there since the 1940s. No doubt the perfect vehicle for giving the pet kangaroo a little outing.
