I saw a picture of it in one of the law enforcement magazines. I belive it was in the Law Enforcement Technologies magazine. It looks similar to todays Tahoe but it has a lowered suspension and it looked like bolt on center cap wheels. Standard motor was the Vortec 5300. I also recall that it did very well at the Michigan State police tests.
The picture of the one that they had was white with a large sticker on the side back windows stating "Pursuit Rated in 2005".
I belive that the artical was in the December issue........
