Clothing where vehicle conks out (7)

I believe the answer is:

cardies

'clothing' is the definition.
(short for cardigans)

'vehicle conks out' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'conks out' becomes 'dies' ('die' can be a synonym of 'conk out').
'car'+'dies'='CARDIES'

'where' acts as a link.

I've seen this clue in The Guardian.
