Mitsibushi Montero TV ad song


My wife's been bugging me about the artist and title.
This is the ad were the drivers are singing along and slapping the palm of their hand on the steering wheel to the beat of the music.
Opens with 2 guys and then a girl with a dog driving.
Thanks!

My son told me it was a Barenaked Ladies song - the title which escapes me . If no one else responds I will ask him when I get home.
Yeah...there is one with a Barenaked Ladies song called, "One Week" (I think that's the title).
