Asian sailor's article for Vegas vehicle (6)
I believe the answer is:
lascar
'asian sailor's' is the definition.
(I've seen this before)
'article for vegas vehicle' is the wordplay.
'article for vegas' becomes 'las' (I've seen this in another clue).
'vehicle' becomes 'car' (car is a kind of vehicle).
'las'+'car'='LASCAR'
(Other definitions for lascar that I've seen before include "Asian sailor" , "The East Indian sailor is a rascal" , "Sailor from overseas" , "Kind of foreign sailor - quite a rascal" , "E. Indian seaman" .)
