Bought a couple of Honda 90 Cub replacement wing mirrors from a chap on Ebay and when they arrived they are not E marked.
As I only bought them for the SVA I'm a bit pissed off. Does it matter?

No - the inspectors are quite relaxed about e-markings on mirrors.

They only need to be the correct height and width, and have the correct radii on the edges.

What he said!

As long as they have similar characteristics as E marked ones they should be fine.
My car passed with non E marked Cub mirrors.

The Cub70 is so old its unlikely mirrors will be E-marked. I've just checked mine and they're not e-marked. Still passed without a problem though

Phew! thanks guys
