Elegant vehicles brought back (5)
I believe the answer is:
smart
'elegant' is the definition.
(similar in meaning)
'vehicles brought back' is the wordplay.
'vehicles' becomes 'trams' (tram is a kind of vehicle).
'brought back' is a reversal indicator.
'trams' backwards is 'SMART'.
(Other definitions for smart that I've seen before include "Clever; sting" , "Well-dressed" , "astute" , "Neat, tidy; sting" , "Neat - clever" .)
