Stylish vehicles turned up (5)
I believe the answer is:
smart
'stylish' is the definition.
(similar in meaning)
'vehicles turned up' is the wordplay.
'vehicles' becomes 'trams' (tram is a kind of vehicle).
'turned up' says the letters should be written backwards.
'trams' in reverse letter order is 'SMART'.
(Other definitions for smart that I've seen before include "Intelligent; clean, tidy" , "Fine" , "Well turned out" , "Elegant and stylish" , "Chic - hurt" .)
