Yeah...boring. Not truly special, except the paint.
We should have something called a M3 SS. Like a vintage muscle car. Special engine/exhaust touches, SS badges on the car, steering wheel, interior, and upholstery. Maybe dropped a bit, distinctive paint scheme. Really embrace the limited edition muscle car theme. Carbon everything: spoiler, mirror caps, "performance" carbon interior trim, new angel eyes (sorry I love my lux and all). Supercharged. Yeah...M3 Super Sport.
