Standard car coat (5)

I believe the answer is:

parka

'coat' is the definition.
(parka is a kind of coat)

'standard car' is the wordplay.
'standard' becomes 'par' (I've seen this before).
'car' becomes 'ka' (Ka is a model of car produced by Ford ).
'par'+'ka'='PARKA'

(Other definitions for parka that I've seen before include "jacket for cold weather" , "Short, hooded coat" , "Hooded waterproof coat" , "warm gear" , "weatherproof cover" .)

I've seen this clue in The Guardian.
