Car in front of Escort, say (6)
I believe the answer is:
estate
'car' is the definition.
(type of car)
'front of escort say' is the wordplay.
'front of' says to take the initial letters (the letter at the front of the word).
'say' becomes 'state' (synonyms).
The first letter of 'escort' is 'e'.
'e'+'state'='ESTATE'
'in' is the link.
(Other definitions for estate that I've seen before include "Property left at death" , "Condition" , "Lands" , "Car; landed property" , "What you leave when you die" .)
