I have these all fitted...and the skid protectors, although they look nice, are just plastic that can be seen a little at the front and a bit more at the back. They are short and don't even extend under the car...basically, very expensive plastic trim!!
The items I liked were the sill protectors (front) and for the boot.
I know it's a matter of taste, but I slso like the chrome finish over the mirrors.
They are all available on mainland Europe...but seem to take a bit longer getting to your shores from the experience of forum members in the UK and take a bit of time to source.
