These retail for around 350 euros

They can be fitted to other models.  The picture of them fitted is a 2016 RHD P3 XC60 .  Its not 100% perfect fit on the accelerator pedal, but pretty darn close. Brake pedal is perfect. So i expect they will be the same for all P3 platform i.e.  XC70 XC60 S60 V60 S80 . 

Bear in mind these are hard to fit irrelevant of model.  strong fingers or boning tools required.

This gives you an idea.
