I believe the answer is:

valet

I'm a little stuck... Click here to teach me more about this clue!

'car?' is the definition.
(I have seen 'Clean car' mean 'valet' so perhaps 'car' could also mean 'valet')

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for valet that I've seen before include "Man's personal attendant" , "dresser" , "Clean inside" , "Man's manservant" , "Male servant" .)

I've seen this clue in the Evening Standard.
