Coupe or convertible (4)

I believe the answer is:

auto

(Other definitions for auto that I've seen before include "Motor vehicle, in short" , "Car (mostly US)" , "Motor car (mainly US)" , "Prefix denoting by or of the same person or thing" , "Car (American)" .)

I've seen this clue in the Newsday.
