Evening Rush Hour Aviero: Faces Squinting in the Sun

I used to see a lot of very attractive buses in Portugal but I have to say these don't figure amongst them. However these seen in 1984 do show a good contrast as the earth-red Volvo on the left is an Aviero town bus, whilst Caetano bodied RN 2455, probably another Volvo, is working a quite long 50km trunk route to Coimbra. My favourite though is the elderly but still very smart royal-blue coloured vehicle overtaking these on the right probably going to some little village nearby but apart from that I know almost nothing.
