Small cars for Middle Eastern folks (6)
I believe the answer is:
saudis
'middle eastern folks' is the definition.
(people from Saudi Arabia)
'small cars' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'cars' becomes 'Audis' (Audi is a car manufacturer).
's'+'audis'='SAUDIS'
'for' acts as a link.
(Other definitions for saudis that I've seen before include "Inhabitants of an Arab kingdom" , "Nationality of citizens living in Riyadh" , "Citizens of Riyadh, nationally" .)
