Nice mods. Congratulations.
Having just acquired my 2020 Plus Four, I too, was struck with just how poor the rear view, and door mirrors are. My dipping black plastic rear view mirror was next to useless providing a foggy indistinct view, whilst my door mirrors are not only already pitting, but are impossible to adjust. On dismantling them I found the inner curved friction plate to be be pitted and rusted which is why they are so difficult to adjust.
Like you I thought the MY25 factory rear view mirror would be a big improvement but regrettably I was too tight to shell out the £250 the factory were asking for it. So instead I fitted the Librands small chrome mirror at £45. Its not as nice as the factory one, and it was a mistake.in retrospect. I also wanted the new factory MY25 door mirrors, but all supply is going to production, so they are unavailable, so I am in a quandary to wait for them or go the Librands route like you.
