Rogue I phone back to get car (8)
I believe the answer is:
cadillac
'car' is the definition.
(I've seen this before)
'rogue i phone back' is the wordplay.
'rogue' becomes 'cad' (I've seen this before).
'phone' becomes 'call' (synonyms).
'back' says the letters should be written in reverse.
'call' backwards is 'llac'.
'cad'+'i'+'llac'='CADILLAC'
'to get' acts as a link.
(Other definitions for cadillac that I've seen before include "Luxury US car" , "Luxury US automobile" , "American brand of luxury car" , "Make an acid call for the US car" , "Car maker" .)
