I finally got hold of a copy of a World Registry of Cobra's and GT40's from SAAC. I've been watching these on eBay for a long time. This one popped up at a good price ($55) and I ended up winning the bid. I've read the first 16 pages and so far it's very interesting, but It's probably not for everyone. I was hoping to read some cool stories and get a better understanding of the history of these cars. 1600 pages of cobras. It would be cool if all the pictures were color. Maybe in the 5th addition.
