Ford knows how to gets the attention of netizens, all you need to to take something they hold dear to their hearts and use it in an advertisement. What follows is a mixture of 'this is awesome' and confusion at watching something like Dragon Ball be used to sell a car.
Of course, neither Krillin, Dende, Gohan or Porunga really need a car in the Dragon Ball universe. They are pretty self-sufficient when it comes to transportation with the flying, giants leaps or super speed. The rest of us, however, require some other form of transportation – whether it's a bike or a car.
The advertisement is only being shown online, but typically we don't see a trailer like this made in English. This is somewhat of an anomaly, although Toyota has a Hatsune Miku Corolla ad mostly in English a few years ago. Either way, it's nice to see Porunga again, even if he's trying to sell us a Ford Focus.
