Irishman grabbing daughter's car (5)
I believe the answer is:
Here is my best explanation:
'car' is the definition.
(sedan is a kind of car)
'irishman grabbing daughter's' is the wordplay.
'irishman' becomes 'sean' (I've seen this in other clues).
'grabbing' is an insertion indicator.
'daughter' becomes 'd'.
'sean' enclosing 'd' is 'SEDAN'.
