The old Fox coupes could pull it off easily, but the spoiler on SN95's looks as though it was integragted into the entire look. They didn't leave the spoiler off on V6's or GTS's for any reason other than cost. They set out to build a really stripped down car so it could fit into really tight budgets.
And don't tell me it was omitted for weight savings, even Ford knows the rear end is NOT where you want to save weight!(to an extent)
