"She's Having a Baby", 1988?, starring Kevin Bacon and Alec Baldwin. An E30 is in 2 scenes. In one scene Kevin Bacon drives it very agressively, revs it in Neutral, burns out, goes in reverse etc. Car is shown for 2 min. max. I could not view the badge clearly, but I'd guess it's a `84-`85 318i - it sure sounds like a 4-cylinder.
