You should include videos of some of the original Z-Car commercials. Keep the pictures to a minimum and don't use your slides as a crutch. In essence, outline/write the speech before you even work on the presentation slides. This way your slides will merely reinforce what your saying rather than it appearing as if your reading the slide to the class. That'll make it interesting. Also engage the class a bit. These are people you know so use that to your advantage. You don't have to have a conversation with the audience or name names but at least attempt to elicit a response. This will cause the audience to feel as if you're conversing with them rather than simply talking 'at' them. A perfect example, if there is some computer nerd kinda kid in the class, show the Wozniak clip and then make the comment: "Maybe we'll see making car commercials in 10 years."
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
