Charlie, at ten, found in vehicle, getting time off (8)
I believe the answer is:
vacation
'time off' is the definition.
(vacation is a kind of time off)
'charlie at ten found in vehicle' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'ten' becomes 'IO' (IO resembles 10).
'found in' indicates putting letters inside.
'vehicle' becomes 'van' (van is a kind of vehicle).
'c'+'at'+'io'='catio'
'catio' placed inside 'van' is 'VACATION'.
'getting' acts as a link.
(Other definitions for vacation that I've seen before include "Leave" , "Holiday period" , "An American holiday" , "Leisure time away from work" , "break" .)
