As a relative newbie here, I have been reading this thread with interest. I got the impression that any warnings were given in a friendly/advisory manner not as a threat of action to be taken by anyone here on the forum. Over the years I have read many books and articles about the S4 Sevens and all too few even acknowledge the NZ built cars, it therefore not surprising that there is little knowledge outside NZ about them. The CAMS reference is irrelevant in as much as we have no idea why NZ built cars were classified as they were in Australia. I doubt anyone involved in any licensing or business transactions with Lotus or Colin Chapman would be willing to have any documentation posted on the net. I only reponded due to my interest in these cars for many years and the desire to own one myself.
