Star rode about in open-top car (8)
I believe the answer is:
roadster
'open-top car' is the definition.
(I've seen this before)
'star rode about' is the wordplay.
'about' indicates anagramming the letters.
'star'+'rode'='starrode'
'starrode' with letters rearranged gives 'ROADSTER'.
'in' is the link.
(Other definitions for roadster that I've seen before include "Small open-top car" , "Open two-seater car" , "Open-topped car" , "sporty car" , "An open car without rear seats" .)
