| on the 'why'. Different sources (a few magazine scans I came across in my earlier searches) that have more general listings like Z32s produced overall and per year for the US match the VIN numbers that I used, leading me to believe their accuracy in the details. Considering that US slicktops were only 2+0 and NA, the ratio of slicktops to 'slicktop-eligible' Z32s was a bit more significant, especially in '91. Slicktops vs. all NA 2+0: 1990 - 0.32% 1991 - 20.45% 1992 - 15.3% 1993 - 6.3% 1994 - 7.9% 1995 - 4.9% 1996 - 14.05% Overall - 6.2% (excluding 1990, 11.5%) This time I won't try to expound on why the numbers came out that way. But I believe they are legitimate.
