I just stumbled across this site. It contains some high resolution scans of sales brochures in pdf
1990 = https://www.gmheritagecenter.com/gm-..._1990_ZR1.html

In searching here, I didn’t find a reference to this specifically on our site (although I may have missed it, so if this is well-known, forgive me)

There are references to other sites with sales brochures as mentioned in these links
http://www.zr1.net/forum/showthread....light=brochure
http://www.zr1.net/forum/showthread....light=brochure
but sometimes the scan quality is poor and the characters are difficult to read.

This link references the GM Heritage site and the Vehicle Information Kit.

It’s a shame this scan is of such low quality, though.

FWIW, if you’re looking for a brochure, this is good online source
