Steering Wheel Material 90'

Hey I was wondering what the steering wheel from a 90' sedan deville is made out of, vinyl or leather, if anybody knows, please help.
Of course the column is plastic, and I think behind the horn casing is vinyl but the front part where the caddi sign is im thinking its leather?

help, Thanx

It's a plastic. Only the hand grips were covered with leather.

Thanx man
