Indestructible limo crashed with tram (8)
I believe the answer is:
immortal
'indestructible' is the definition.
(thesaurus)
'limo crashed with tram' is the wordplay.
'crashed with' is an anagram indicator.
'limo' anagrammed with 'tram' gives 'IMMORTAL'.
(Other definitions for immortal that I've seen before include "never to be forgotten" , "Moral Tim (anag.)" , "Never dying" , "Living for ever" , "Not subject to death" .)
