Turning to USA for cars? (5)
I believe the answer is:
'for cars?' is the definition.
('auto' can be a synonym of 'car')
'turning to usa' is the wordplay.
'turning' is an anagram indicator.
'tousa' with letters rearranged gives 'AUTOS'.
(Other definitions for autos that I've seen before include "Cars" , "Religious dramas" , "Freeway traffic" .)
