Turns over a good car (5)
I believe the answer is:
rolls
This could be a double definition.
'turns over' is the first definition.
('roll' can be a synonym of 'turn over')
'a good car' is the second definition.
'rolls' can be an answer for 'car' (short for Rolls Royce). I'm not sure about the 'a good' bit.
Can you help me to learn more?
(Other definitions for rolls that I've seen before include "Lists of names of members" , "Moves by turning" , "Turns over - luxury car (abbr)" , "Baps - posh car" , "Bread portions" .)
