Times cryptic, old, found in a vehicle? Not inclined to indulge (10)
I believe the answer is:
abstemious
'not inclined to indulge' is the definition.
'times cryptic old found in a vehicle?' is the wordplay.
'cryptic' is an anagram indicator.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'found in' means one lot of letters goes inside another.
'vehicle?' becomes 'bus' (bus is a kind of vehicle).
'times' is an anagram of 'stemi'.
'stemi'+'o'='stemio'
'a'+'bus'='abus'
'stemio' put within 'abus' is 'ABSTEMIOUS'.
(Other definitions for abstemious that I've seen before include "not eating or drinking a lot" , "Self-denying" , "Temperate" , "I mess about (anag.)" , "in a way that's restrained" .)
