Tried car home for a change, parking within sight of Paris (3,2,8)
I believe the answer is:
arc de triomphe
'sight of paris' is the definition.
'tried car home for a change parking within' is the wordplay.
'for a change' is an anagram indicator.
'parking' becomes 'p'.
'within' is an insertion indicator.
'tried'+'car'+'home'='triedcarhome'
'triedcarhome' is an anagram of 'arcdetriomhe'.
'arcdetriomhe' placed around 'p' is 'ARC DE TRIOMPHE'.
(Other definitions for arc de triomphe that I've seen before include "war memorial" , "Famous monument" , "Feature in Paris" , "Parisian landmark" , "Central Paris landmark" .)
