Billions lost from rubbish repair shop (6)

I believe the answer is:

garage

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

'repair shop' is the definition.
(garage is a kind of repair shop)

I can't explain the remainder of the clue.

(Other definitions for garage that I've seen before include "Car port" , "Observation" , "Car storage area" , "workshop" , "Car shed" .)

I've seen this clue in The Times.
