Facility within plain car such as Bond might relish? (3,7)
I believe the answer is:
dry martini
'such as bond might relish?' is the definition.
(James Bond drinks Martinis)
'facility within plain car' is the wordplay.
'facility' becomes 'art'.
'within' indicates putting letters inside.
'plain' becomes 'dry'.
'car' becomes 'mini' (Mini Cooper**).
'dry'+'mini'='drymini'
'art' put into 'drymini' is 'DRY MARTINI'.
(Other definitions for dry martini that I've seen before include "Gin-based cocktail" , "drink" .)
