Lee, if my memory serves me well, which it doesn't, there were more than 3 of these cars in the Porsche tent. I think they had a couple of "T" cars in there as well.
It's a shame I didn't have a camera with me on that night, but this was pre digital days and I couldn't be trusted with SLR's and limited footage.
Maybe Fax knows a bit more about the Stuttgart strategy that year...
