"1991 - saw the addition of the SHO Plus model. It had a fiberglass hood, 24 Valve DOHC emblems on the side, and the first year of the body colored "TAURUS" logo on the trunk lid, many received updated rod shifter."
I think 1991 was the only year for the Plus. After that a lot of "Plus" options became standard.
