Vehicle found in Nicaragua (3)
I believe the answer is:
car
'vehicle' is the definition.
(I know that car is a type of multi-track vehicle)
'in nicaragua' is the wordplay.
'in' indicates a hidden word.
'CAR' is hidden within 'nicaragua'.
'found' is the link.
(Other definitions for car that I've seen before include "saloon perhaps" , "Hatchback, say?" , "Wheels" , "Private transport" , "Railway carriage; vehicle" .)
