Small car for Middle-Easterner (5)
I believe the answer is:
saudi
'middle-easterner' is the definition.
(I've seen this before)
'small car' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'car' becomes 'audi' (Audi is a German car brand).
's'+'audi'='SAUDI'
'for' is the link.
(Other definitions for saudi that I've seen before include "Native of kingdom" , "Asian" , "Middle-Easterner" , "Arab" , "from the Middle East" .)
