From the 2000 CAMS Manual, Section 11 Page 52

1. ELIGIBILITY
For a vehicle to be eligible as a Production Rally Car, it must be derived from any of the following:

1.1 Cars recognised by the FIA as being of Group A from January, 1982.

1.2 Cars formerly recognised by FIA as being of Group 1 or Group 3 which are included on lists published prior to 31 December, 1981.

1.3 Cars recognised by CAMS as an Australian Touring Car, in their basic form.

1.4 Cars recognised by CAMS as a Series Production Car for Group 3E racing whether currently or previously and if the latter, having been deleted only due to the cessation of production.

1.5 Cars marketed in Australia being either manufactured or assembled in Australia or fully imported, and being of a model which CAMS in its sole descretion may recognise as a production rally car irrespective of the number produced or of its origin, and subject to the model being deemed by CAMS to be within the spirit of the definition of a mass produced vehicle.

Damn this is confusing. Can someone who legally rallies an A14 powered Datsun 1200 in PRC come forward and tell us how you did it?! (IF it is legal)

Any ideas 1200rc?
