Brazilian vehicle, one local uncovered (7)
I believe the answer is:
carioca
'brazilian' is the definition.
(Carioca means a resident of Rio de Janeiro)
'vehicle one local uncovered' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'one' becomes 'I' (Roman numeral).
'uncovered' says to take the centre.
The centre of 'local' is 'oca'.
'car'+'i'+'oca'='CARIOCA'
(Other definitions for carioca that I've seen before include "Latin dance" , "Samba-like dance" .)
