1989 Arizona DPS SSP T-114

[ImEvil1]

Per the 1989 SSP Brochure, you could order cars with the "black-out delete" treatment on the wheels.

The prior year brochures do not make mention of that option, so it could have been an '89-only deal (especially since they went to the silver as standard the following year).
