Bargain smallish car seen on Route 66? (7)
I believe the answer is:
compact
'bargain' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for compact that I've seen before include "Make denser, agreement" , "bargain" , "Little" , "Dense; treaty" , "Small case for face-powder" .)
