Do your research, the Super Edition was a limited run for 88 and 89, not confirmed but likely were around 200 produced for each year.
In 88 they were a special white/gold two tone colour scheme, momo wheel and shift knob and half leather seats, but were otherwise the same as a G-Limited Super Charger model.
In 89 they did another run with a modified blue (standard was 8E3, Super Edition was 8E4) colour, but this time they also added Recaro LX style seats and matching door cards. The 89's were more desireable too since the '89 model AW11 came with a heap of goodies like Aero mirrors, mirrored targa tops, LED brake light on the spoiler.
