Allow me to give another shout out to Kevin Marti. With his reports we are able to confirm the remaining 1988 SSP Mustangs from Pierce County Sheriff's Department. They ordered different color cars this year:
Cabernet Red . . .11 units
Oxford White . . . 5 units
Light Grey . . . . 1 unit
Med Shadow Blue. . 1 unit
--------------------------------
. . . . . . . . . 18 units total
Take a look at the
1988 VIN Page and scroll down to JF256164. Although I no longer own a PCSD car, I am glad to have been able to confirm the entire 1988 batch.
