While waiting for the Marti Reports to confirm the 32-car batch containing the 1986 FBI car, along with reports for TxDPS (from 1983, 1984, and 1986) and FHP (1988), I thought I would post up a recent addition. Here is the page on a 1989 government/GSA Mustang -

This is the 3rd GSA SSP to turn up in that batch of 138 cars, which also contains a likely OSP Mustang at the beginning.
