He exits the trunk of the car by ripping through the back seat(s) then uses the car phone to call the apartment. The phone rings, the bad guys answer and kaboom. Porter, his girl and her dog drive away with a bunch of cash...

Stegman: You know what, Val, this one's on me. OK?
Val Resnick: Do you see me reaching for my fucking wallet?
Trivia: The tagline for this film, "Get ready to root for the bad guy," was changed for the Australian release to "Get ready to cheer for the bad guy" after Mel Gibson pointed out the other meaning of the word "root" in Australian slang (to have sex) to the producers.
