Car India developed offering shower — that's far from basic! (4,4)
I believe the answer is:
acid rain
'shower that's far from basic' is the definition.
I can't judge whether this definition defines the answer.
'car india developed' is the wordplay.
'developed' indicates anagramming the letters.
'car'+'india'='carindia'
'carindia' is an anagram of 'ACID-RAIN'.
'offering' acts as a link.
Can you help me to learn more?
(Other definitions for acid rain that I've seen before include "Polluted water" , "that pollutes" , "environmental problem" , "Damaging precipitation" , "Destructive precipitation" .)
