Two gentlemen lost in a desert think many amazing things are mirages, not worth their energy, in the latest new spot for the Fiat 500L, created by Doner. Those amazing things include a car full of hot girls -- and a Fiat driven by Sean "Diddy" Combs.

The global spot also gives a shoutout to Diddy's "Revolt" venture: a soiree hosted by the rap star is where the two guys eventually head up.

At the party, one of the guys emphatically announces that this has to be a mirage, despite signs to the contrary, because a Fiat nearby has four doors, and the brand doesn't make big cars.

Pharrell Williams' "Happy" provides soundtrack.
