Cocktail made with skill in small car (7)
I believe the answer is:
martini
'cocktail' is the definition.
(martini is a kind of cocktail)
'skill in small car' is the wordplay.
'skill' becomes 'art' (I've seen this before).
'in' indicates putting letters inside.
'small car' becomes 'mini' (I've seen this before).
'art' put into 'mini' is 'MARTINI'.
'made with' is the link.
(Other definitions for martini that I've seen before include "Gin or vodka with dry vermouth" , "Alternative name for Simone Memmi, pre-Renaissance Italian painter" , "rifle" , "Cocktail made with gin or vodka and vermouth" , "tipple" .)
