Ohh, I love this...It's The Song...
La Raza by Los Rabanes

It's in (mostly) Spanish and talks about gathering up all the Latin race to be together and womanize...lol I know - I'm a junior in high school w/ Spanish III and couldn't belive that's what they are singing about - lte alone imagine it to be in a car commercial, but it is catchy - good choice Pontiac!
