I saw a movie when I was a kid mid/late seventies roughly, the protagonist drove a Porsche 911 white with racing decals. He had to drive to deliver stuff to get a kidnapping victim back. one seen I remember is he raced a bunch of muscle cars and won, after the race a guy walks up to the front of the car and and ask what's under the hood, the Porsche driver opens the front hood and says Twinkies, and there are boxes of Twinkies. Anyone know the name of that movie?
