Care terribly about condition for vehicle (6,3)
I believe the answer is:
estate car
'vehicle' is the definition.
(estate car is a kind of vehicle)
'care terribly about condition' is the wordplay.
'terribly' is an anagram indicator.
'about' means one lot of letters goes inside another.
'condition' becomes 'state' (the state something is in).
'care' with letters rearranged gives 'ecar'.
'ecar' going around 'state' is 'ESTATE-CAR'.
'for' is the link.
(Other definitions for estate car that I've seen before include "Vehicle with five doors" , "employed at Sandringham?" , "Brake" , "Capacious vehicle" , "Vehicle with large area for goods" .)
