Car was leaking endlessly, in condition to be picked up (7)
I believe the answer is:
audible
'in condition to be picked up' is the definition.
(able to be heard or picked up)
'car was leaking endlessly' is the wordplay.
'car' becomes 'audi' (Audi is a German car brand).
'was leaking' becomes 'bled' (bleed can mean to leak something).
'endlessly' means to remove the last letter.
'bled' with its final letter removed is 'ble'.
'audi'+'ble'='AUDIBLE'
(Other definitions for audible that I've seen before include "Able to be heard" , "Easily caught" , "Capable of being heard" , "Within hearing range" , "Distinct" .)
