Moves a car (5)
I believe the answer is:
rolls
I believe this clue is a double definition.
'moves' is the first definition.
(rolling is a kind of moving)
'a car' is the second definition.
(short for Rolls Royce)
(Other definitions for rolls that I've seen before include "Some bread; trills (an r)" , "Moves by turning" , "flash car" , "Lists of names of members" , "Bread portions" .)
