@Montero: about the scene, where the Pajero drive across the flat water, I am not really sure, but the others are quite surely made in Southern Africa, perhaps Namibia. Ground and vegetations are looking like that.
The only "Namibian chance" for the beach-scene would be the beach north of Lüderitz, otherwise the coast is too rough over there. Or its not possible to reach it.
It's very common for car-brands to make the pics for commercials and sales brochures in Southern Africa. Fascinating, foreign looking landscapes, good light (because dry climate), infrastructure and at least cheap prices.
When we made vacations in Namibia in March 2006, we saw a convoi of around 20 Audi Q7, Audi A8 and VW Eos, going North to the National Parks.
Yes, it's often very difficult or tricky to collect movie-songs in the movie-version.
For years I looked for the theme of that
movie, I like a lot:

I only had a bad selfmade VHS-tape-copy of this film. For a lot of years there was no video- or DVD-release of it. And in the pre-Youtube-time there was no chance to get the song somewhere.
A guy, one of the craziest 60ies- and 70ies-music-collectors, told me, that the original song "The Brain" of "The American Breed" was released only one time, on the B-side of annother song and annother time, on one French sampler of 60ies-music.
Some months ago I found the Youtube of it - but the song-version, not the movie-version with the machinegun-sound in the background.
Does anyone here remember the Wrigley's Spearmint-commercial of the lates 70ies ("Wrigley's Spearmint gum, gum gum....")? There the people carried oversized chewing-gum-packets with them.
That music-freak has told me, that no orginal record of this song is existing any more, to tape, nothing. Only old videos of the spot itself.
