That is the same exact sticker you see on the dash in the Caprice cop cars.
I had just left the local coffee stop one morning and a few of the other guys stayed behind long enough to see the Buffalo Police Undercover Narc squad roll in (about 8-10 guys)to coordinate a raid they were going to do somewhere nearby.They guys said the cops had a real nice 87 GN they were using,probably as a chase vehicle,I don't know but it was somehow involved with the enforcement end of this situation.They spoke for a while, then left,all were wearing BPD T-shirts.There were other vehicles involved but just pedestrian types.There was no indication at all on this vehicle that it was Police from what they could tell,no even the plates. One of the guys had a Ttype and a GN before this,so he knows what he saw.I figure it was obtained during a previous raid,the money is not there for stuff like this otherwise.I have never seen it but you got to wonder who will end up owning it in the long run.Probably auction it but first give dibbs to cops and insiders before the public even sees it.
