Heres a new vehicle (6)
I believe the answer is:
hearse
'vehicle' is the definition.
(hearse is a kind of vehicle)
'heres a new' is the wordplay.
'new' indicates anagramming the letters.
'heres'+'a'='heresa'
'heresa' with letters rearranged gives 'HEARSE'.
(Other definitions for hearse that I've seen before include "Car for carrying a coffin" , "Undertaker's car" , "Funeral car" , "Funeral carriage" , "Funeral vehicle" .)
