On my 2005 95 2.3t Vector sport saloon the rear silence box is peeling and does not look good. But my very reliable indy garage reassured me at the MOT (last Dec) that this is not a problem. The inner skin is visible in parts and looks ok. Any experience or advice on this? The garage will check it this week and, of course, it always happens just before a long trip somewhere (this time Germany)...
