Large car from Spain, say (6)
I believe the answer is:
estate
'large car' is the definition.
(I've seen this before)
'spain say' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'say' becomes 'state' ('state' can be a synonym of 'say').
'e'+'state'='ESTATE'
'from' acts as a link.
(Other definitions for estate that I've seen before include "Property with large grounds" , "Desmesne" , "Houses - car" , "The whole of a deceased person's assets" , "One's property after death" .)
