Car attendant (6)
I believe the answer is:
escort
I believe this clue is a double definition.
'car' is the first definition.
(Ford Escort is a type of car)
'attendant' is the second definition.
(I know that escort is a type of attendant)
(Other definitions for escort that I've seen before include "Accompany (a person)" , "giving protection" , "Accompany, to protect perhaps" , "Bodyguard" , "Go with (someone)" .)
