The 230 special edition should have a Kompressor but on that model they left off the Kompressors badges. I think the main differences with this edition are all cosmetic - different alloy wheels, polished aluminium centre console, different gear knob, black surrounds to the fan heater controls instead of cream, instrument needles have aluminium centres and nappa leather interior.
