1993 no. 170 was a CPC mule but for what ?

[falconfling]

My build sheet shows it was "born" late Dec. 22, 1992 and sent off to CPC.
for about 3 years and 19,000 miles. Build is noted "This car was built for a particular purpose or person". The first non GM owner got it from a dealer in Atlanta and tells me the front tires were almost slick and the pass. side rear wheel and tire replaced. He threw away what apparently was the cars log book, but did keep an ECM chip which he says is "signed"....???
Hope he can find it and send to me. Remaining on the car are the CPC sticker: "Remove if reassigned or sold" and a bundle of leads coming from deep in the engine comparment and ending at the firewall. Comments on what "testing" this one might have been involved in ??? ...or is there a GM guy who remembers this white 1993 from their days at Warren ?
