Chaps eventually go around to collect Italian vehicle (5)

'italian vehicle' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'chaps eventually go around to collect' is the wordplay.
'to collect' says the answer is hidden in the clue (I've seen 'collecting' mean this).
'go around' says the letters should be written backwards (I've seen 'going around' mean this).
'apsev' can be found hidden inside 'chaps eventually'.
'apsev' in reverse letter order is 'VESPA'.

Can you help me to learn more?
