Hard to find vehicle near small church (6)
I believe the answer is:
scarce
'hard to find' is the definition.
(I've seen this before)
'vehicle near small church' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'near' means one lot of letters go next to another (I've seen this in other clues).
'small' becomes 's' (abbreviation - e.g. clothes size).
'church' becomes 'ce' (Church of England).
'car' put after 's' is 'scar'.
'scar'+'ce'='SCARCE'
(Other definitions for scarce that I've seen before include "exceptional" , "Like gold dust" , "Not often come across" , "Insufficient to meet demand" , "Not plentiful, in short supply" .)
