Rearview mirrors for a Greyhound

[R Warlop]

One mirror inside isn't safe enough i.m.h.o and I have seen several wing/door mounted mirrors being added.
   in your view, what is the best design and the least intrusive place to position them?
   For example:

We originally had clip-on ones on the quarterlights, but that was impractical if you wanted fresh air in the car:
   
   
   
   But decided that the most inobtrusive mounting point(which means NOT having to drill into the bodywork either) is in front of the quarterlight:
   
   
   
   The nearside one is slightly obscured, but generally the view is pretty good, and the appearance is pretty tidy.
   I think we got them at the NEC Classic, but MOSS & G.S.Jones appear to have similar, or search for "Morris Minor Mirrors" on Google, but please don`t admit to 'Toad' parts to an AC!
