Animal found in car (6)
I believe the answer is:
jaguar
I believe this is a double definition.
'animal' is the first definition.
(I've seen this before)
'car' is the second definition.
(I have seen 'posh car' mean 'jaguar' so perhaps 'car' could also mean 'jaguar')
'found in' acts as a link.
(Other definitions for jaguar that I've seen before include "Panther's relative - driven on the road" , "Large cat of tropical America, or fast car" , "Large jungle cat" , "Spotted feline and posh car" , "Powerful cat" .)
