French race track's finale elevated by South African representative, perhaps (8)
I believe the answer is:
salesman
'track's finale elevated by south african representative perhaps' is the definition.
I can't judge whether this defines the answer.
'french race' is the wordplay.
'french' becomes 'sales' (I can't justify this - if you can you should believe this answer much more).
'race' becomes 'man' (I've seen this before).
'sales'+'man'='SALESMAN'
(Other definitions for salesman that I've seen before include "Male shop worker" , "Famous play by Arthur Miller 'Death of a . . . . . . . .'" , "He sells strange lean mass" , "He's a seller" , "''Death of a ...'' (drama by Arthur Miller)" .)
