Hadn't noticed that before.
That would help stop leaves etc getting into the heater fan...!
You'd think but it doesn't.. Mesh on top of the fan unit is the only way to stop leaves getting in as far as i can tell, something i keep meaning to try but other things always seem more important to get done
Pretty sure my cinq has the plate above the headlight and has a plate on the boot floor, i certainly have seen the plates in the boot before.
