Preacher reportedly punctured car (4,6)

I believe the answer is:

holy roller

I'm a little stuck... Click here to teach me more about this clue!

'preacher' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?

'reportedly punctured car' is the wordplay.
'reportedly punctured' becomes 'holy' (I can't justify this - if you can you should believe this answer much more).
'car' becomes 'roller' (I've seen this before).
'holy'+'roller'='HOLY ROLLER'

Can you help me to learn more?

I've seen this clue in The Telegraph.
