Most probably an Aussie advert never seen that one on anyUK television station. I might be wrong but I have never seen a Rav4 advert on UK TV.(I bet Scott knows if I am right or wrong regarding that one)
It is definitely a NZ ad. It can't be Aussie as all Aussie RAV4 ads feature the RAV4 camel. It is the guy who sang mambo no 5. His name is lou bega. The song in the ad is called beauty on the tv screen.
