Something that's left after death in car? (6)
I believe the answer is:
estate
I believe this is a double definition.
'something that's left after death' is the first definition.
(as in a deceased person's estate)
'car?' is the second definition.
(type of car)
'in' is the link.
(Other definitions for estate that I've seen before include "Piece of land with a lot of houses" , "All that one owns at death" , "Desmene" , "Follow on" , "all the deceased owned" .)
