Possibly avoid used car -- I'd not get pinched (10)
I believe the answer is:
cadaverous
'pinched' is the definition.
('cadaverous' can be a synonym of 'pinched')
'possibly avoid used car i'd not' is the wordplay.
'possibly' indicates anagramming the letters.
'not' indicates named letters should be taken away.
'avoid'+'used'+'car'='avoidusedcar'
'avoidusedcar' with 'id' taken out is 'avousedcar'.
'avousedcar' with letters rearranged gives 'CADAVEROUS'.
'get' is the link.
(Other definitions for cadaverous that I've seen before include "Thin and bony like a corpse" , "Unhealthy-looking" , "Gaunt" , "Resembling a corpse" , "Corpse-like" .)
