List includes bill for car (8)
I believe the answer is:
roadster
'car' is the definition.
(roadster is a kind of car)
'list includes bill' is the wordplay.
'list' becomes 'roster' (roster is a kind of list**).
'includes' means one lot of letters goes inside another.
'bill' becomes 'ad' (advertisement stuck on wall).
'roster' enclosing 'ad' is 'ROADSTER'.
'for' is the link.
(Other definitions for roadster that I've seen before include "Old car" , "An open car without rear seats" , "Small open-top car" , "Open two-seater car" , "sporty vehicle" .)
