Nick here is going to talk to you today about his Buick Regal Grand National. This guy grabbed us as we were snapping some pictures of the black-as-night muscle cars as they were ready to head out and cruise Woodward Avenue, and urged us to take a look at his intercooled piece of motown metal. And we're glad he did — as he gives us the story of how an intercooler works, and why the Grand National gets attention at the tracks — and why it should be getting more.
