When you mention the manual idle speed adjustment knob on the 240D's dash, do you mean the small flat knob on the left side of the instrument binnacle under the dials that you twist either right or left? If so The 300D's I've test driven both had this and I recall my cousin's two 300D's in Australia also had them. Or is there another "knob" of which I'm unfamilliar?
