Love to find a vehicle in a musical instrument (7)
I believe the answer is:
ocarina
'musical instrument' is the definition.
(ocarina is a type of wind instrument)
'love to find a vehicle in a' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'to find' means one lot of letters go next to another.
'a vehicle' becomes 'car' (car is a kind of vehicle).
'o'+'car'+'in'+'a'='OCARINA'
(Other definitions for ocarina that I've seen before include "Terracotta wind instr." , "it's blown in pieces" , "Small egg-shaped wind instrument with holes for the fingers" , "Inca oar made into a musical instrument" , "music-maker" .)
