Celebrity's vehicle makes one deeply impressed (4-6)

I believe the answer is:

star-struck

'one deeply impressed' is the definition.

'celebrity's vehicle' is the wordplay.
'celebrity's' becomes 'stars' (I've seen this in other clues).
'vehicle' becomes 'truck' (I've seen this before).
'stars'+'truck'='STAR-STRUCK'

'makes' is the link.

I've seen this clue in The Telegraph.
