Hard to find, some miss car centre (6)
I believe the answer is:
scarce
'hard to find' is the definition.
(I've seen this in another clue)
'some miss car centre' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'SCARCE' is hidden in the letters of 'miss car centre'.
(Other definitions for scarce that I've seen before include "Not enough to meet demand" , "Common? Definitely not" , "exceptional" , "Deficient in quantity" , "Rarely found" .)
