I don't think that, not giving a list of all modes with applicable
manufacturing dates (as, for example, the German equivalent site does)
is "opaque".

This is one occasion where a lookup by numberplate would be appropriate.

Although I've not had a lot of luck with such searches recently.
According to the gadget in Halfords last week my car only has rear wiper
blades (I wanted front) and only has headlight bulbs (I wanted a brake
light).
