The interior plastics on my '98 A3 1.8T are a little untidy in places. The trim that sorrounds the stereo/climate control is blue but some of the colour has rubbed of revealing the black below it. Audi no longer sell this part in blue, only black. Unfortunatley the ash tray and tray behind the gearstick match it. Also the plastic sorrounding the window switches on the doors is chipped and a little worn. Has anyone replaced any of this lot? Did it look good? How much did it cost?
