When I was at the dealership buying my Beetle, one of the sales guys said something about the speakers changing colors-from red to blue to white. At the time I thought he meant I could buy an aftermarket speaker cover. It wasn't until later that I discovered I had a switch that would change it (in my defense, the darned thing was hiding behind my blinker handle on the steering wheel). I'm ashamed to say how much time I spent sitting in my car at night just for the joy of changing the colors out.
