Loads of motor works (7)

I believe the answer is:

'loads' is the definition.
(I know this)

'motor works' is the wordplay.
'motor' becomes 'car' (informal term for car).
'works' becomes 'goes' ('go' can be a synonym of 'work').
'car'+'goes'='CARGOES'

'of' is the link.

(Other definitions for cargoes that I've seen before include "Ships' loads" , "Carried loads" .)

I've seen this clue in the Irish Independent and The Irish News.
