sedan; hatchback from 1989; black exterior trim with red accents, LT emblems, 14 inch styled steel wheels, touring tires, deluxe steering wheel and the FE2 sport suspension (1989 brochure p.8), while the 1988–1989 option-weight pages give F41 as the sport suspension included with the LT; the 1988 option-weight page prints ZII; the 1990 option-weight page still lists the entry (printed 211), but the 1990 order guide sells the LT as models 1LT68 and 1LT69, so 1990 is not claimed
