Did buick make a 1985 black regal t type?

Buick did not make a Regal T-Type in 1985. The T-Type was a trim level/performance package offered on the Buick Grand National, which was a model *derived* from the Regal, but was distinct. The Grand National *was* available in black in 1985. So while there wasn't a "Regal T-Type," a black Grand National was a possibility.
