I've had the centre cover off, no problem, its held on with common rubber fasteners I have seen on several cars I have owned.
But I wonder if at some time the plastic push fasteners will break with use and at that point do you bother putting all the shielding on. Don't know?. Time will tell.
I agree, it does look nice.
It was a bit of a laugh when the neighbour came over to look at the car, when I told him it was a V6 he asked for a look, we both laughed as we looked under the bonnet, underwhelming or what?
