A good crossover
http://www.youtube.com/watch?v=QKpzU2GSVC0 Usually I find cross promotions annoying at best, awkward and forced at worse.
This is the rare cross promotion that I think works for both products. It shows off some neat Godzilla special effect and shares something about the Fiat (surprisingly big). It fits the tone of other Fiat commercials, gives us some humor (craving Italian) and is on-message.
