Service vehicles from Italy, it's said (7)
I believe the answer is:
vespers
'service' is the definition.
(vespers is a church service)
'vehicles from italy it's said' is the wordplay.
'vehicles from italy' becomes 'Vespas' (Vespa is an Italian scooter brand).
'it's said' indicates a 'sounds like' (homophone) clue.
'vespas' sounds like 'VESPERS'.
(Other definitions for vespers that I've seen before include "Evensong - RC service" , "An hour of worship" , "Evening service" , "Evening prayers" .)
