Sports car has a couple of main terminal leads (3-6)
I believe the answer is:
two-seater
'sports car' is the definition.
(I've seen this before)
'a couple of main terminal leads' is the wordplay.
'a couple of' becomes 'two' (a couple is two things).
'main terminal leads' becomes 'seater' (I can't explain this - if you can you should believe this answer much more).
'two'+'seater'='TWO-SEATER'
'has' is the link.
Can you help me to learn more?
(Other definitions for two-seater that I've seen before include "Small car" , "Sports car" .)
