Go round one base for car makers (5)
I believe the answer is:
turin
'base for car makers' is the definition.
I can't tell whether this defines the answer.
'go round one' is the wordplay.
'go' becomes 'turn' (as in one's go or turn in a game).
'round' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'turn' enclosing 'i' is 'TURIN'.
Can you help me to learn more?
(Other definitions for turin that I've seen before include "It. city housing shroud" , "Italian city with famous religious Shroud" , "Italian destination" , "regional capital" , "Piedmontese capital" .)
