It would be nice. The last revision, which I stupidly bought, was the old version with a new cover. In the meantime, the SA World Registry has the best list of all of them, but it costs quite a bit of money. This is fair, IMHO; the amount of work they did was formidable and the number of potential sales not that great. It is very well done, and I highly recommend it. (full disclosure- two of my cars, my GT40 and my Kirkham Cobra, are in it)
