Back to annoying things...
Not so much annoying as amusing (or perhaps confusing?), when looking at pictures of the recent Tan Hill run, the majority of the cars didn't have grille muffs fitted, despite the fact the temperature on the day was between 3 & 4 Centigrade.
If they are needed, which Citroen seemed to believe was the case, surely that's the sort of weather when they should be fitted.
