The Z4 has only been on the market now since 2009, but BMW
is already preparing a minor update for the roadster. At least, that's what it appears from this latest batch of spy shots. The hard-top convertible seen here is only wearing a small amount of camouflage, but its location tells us where the German automaker is focusing its attention. Those updates appear to center around the headlights, tail-lights and side vents, with the rest apparently carrying over unchanged.
