Bar or car? (6)
I believe the answer is:
saloon
This clue is a double definition.
'bar' is the first definition.
('saloon' can be a synonym of 'bar')
'car?' is the second definition.
(I've seen this before)
'or' is the link.
(Other definitions for saloon that I've seen before include "Bar room" , "Boozer or shape of car" , "Pub room" , "Car with separate boot" , "Lounge bar" .)
