Ahh, I didn't know the Rutherford Escort was used as the basis for the body. Was this the brown MkII Mark raced?

It was a bloody ambitious car, to have been created from scratch as a space-frame car. Even though US space-frame cars first appeared in NZ in late 1975 and the merits for building cars this way was obvious, even by the early '80s the popular method was still for taking a road car and modifying it for racing. Most Sports Sedan and OSCA cars at this time were still being built this way when you built your space-frame car. So it was a really ambitious project.
