It will be interesting to see what happens with the GM racing program in the next season or two. I see today that they posted a 1.6 BILLION dollar loss for the 3rd qtr. and their credit rating has been lowered to "junk" status. Hmm, maybe the Cadillac will be next in that regard...
I say, continue to invest in the C6-R in GT1 and put the SWC caddy back as a luxo-cruiser where it belongs (after all, does anyone really spend the $58K required for a "performance" version of a Cadillac?) and go from there.
