I'm surpised I or no one else thought of this earlier... "Pretty In Pink", 1986, starring Molly Ringwald, Andrew McCarthy and James Spader. Features a `84-`86 BMW E30 Coupe. I seem to think it's a 325 (sounds like a 6-cylinder, and seem to recall seeing 325 on the rear) - there's a chance it's a 318i. It's driven by one of the main characters (Blane - Andrew McCartney) - only used in three scenes. A few nice shots of car. No special driving performed.
