Provide only a buggy? (3,2)
I believe the answer is:
lay on
'provide' is the definition.
(I've seen this before)
'only a buggy?' is the wordplay.
'buggy?' is an anagram indicator (I've seen 'buggy' mean this).
'only'+'a'='onlya'
'onlya' with letters rearranged gives 'LAY ON'.
(Other definitions for lay on that I've seen before include "Provide (food, etc)" , "instruction for Macduff" , "Provide (something)" .)
