square headlights were available on gti's i owned on it was an 88. they didn't come as standard equipment until the 90 gti's then those had the four round headlights, things to look for that identify it as a gti are the red pin stripe all the way around on the interior, no door side moldings, and the roof mount antenna. those are distinct on only gti's if it missing those then it most likely is a fake, none the less it was the same car.
