correct me if i'm wrong but not all audis have the leds in the headlamps (if you're referring to those on the r8, a5, ...). by your logic, the audi leds which you base your argument off of are only used in the "higher end" audis that not even the lower end audi's can add-on with an option upgrade...at least the bimmers can add it on and not look so out of place (an a3 with leds in the headlamps would look kind of weird).
i was looking up the a3 and man these 18" wheels look familiar...
