The range of a sedan, maybe (5)
I believe the answer is:
andes
'the range' is the definition.
(South American mountain range)
'a sedan maybe' is the wordplay.
'maybe' is an anagram indicator.
'sedan' with letters rearranged gives 'ANDES'.
'of' acts as a link.
(Other definitions for andes that I've seen before include "Major mountain range" , "Great S American mountains" , "South American mountain range" , "South American mountains" , "Mountains for the Danes, oddly" .)
