Jack perhaps leaving daughter an old banger? (3)
I believe the answer is:
car
'an old banger?' is the definition.
'jack perhaps leaving daughter' is the wordplay.
'jack perhaps' becomes 'card' (jack is a playing card).
'leaving' suggests deleting specific letters.
'daughter' becomes 'd'.
'card' with 'd' taken away is 'CAR'.
(Other definitions for car that I've seen before include "4-wheeled vehicle" , "Automobile" , "Means of transport" , "Auto" , "estate, perhaps" .)
