Money put aside to repair GIs' vans (7)
I believe the answer is:
savings
'money put aside' is the definition.
(I've seen this before)
'repair gis' vans' is the wordplay.
'repair' is an anagram indicator (letters are fixed or repaired).
'gis'+'vans'='gisvans'
'gisvans' is an anagram of 'SAVINGS'.
'to' acts as a link.
(Other definitions for savings that I've seen before include "Cash put by" , "Money put aside" , "A nest egg" .)
