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'.
(Other definitions for sedan that I've seen before include "Enclosed chair", "Portable chair", "Litter", "Chair to be carried by two", "Covered chair carried between poles", "Four-door car", "Palanquin; car", "Saloon car in America", "Old portable chair for Danes" and "Once a mobile chair for Danes".)
