Took the car to Dover, unusually (5)
I believe the answer is:
drove
'took the car' is the definition.
(I've seen this in another clue)
'dover unusually' is the wordplay.
'unusually' is an anagram indicator.
'dover' with letters rearranged gives 'DROVE'.
'to' acts as a link.
(Other definitions for drove that I've seen before include "Herd of cattle" , "Moving flock; forced" , "took to the road" , "Motored; moving flock" , "Urged, flock on the move" .)
