The vehicle one got rid of has gone (8)
I believe the answer is:
vanished
'gone' is the definition.
(I've seen this in another clue)
'the vehicle one got rid of' is the wordplay.
'the vehicle' becomes 'van' (type of vehicle).
'one' becomes 'i' (Roman numeral).
'got rid of' becomes 'shed' (shed can mean to lose or cast off).
'van'+'i'+'shed'='VANISHED'
'has' is the link.
(Other definitions for vanished that I've seen before include "gone" , "disappeared from view" , "Disappeared without trace" , "disappeared from sight" .)
