I hear an echo in all the reads.
Beer can – vary the energy like you did with Pepsi.
Cadillac – you need a more luxurious and or take-charge read, GET OUT OF THE WAY !!!
Pepsi – ohmygawd you are perfect for this. I would consider embracing the quirky, cutesy type of commercials. Done right, they are a lot of fun, and can get get a lot of attention. It fits your personality.
With you success !
