This is what I wrote in a reply probably where you got that info:
Hi,
cool car indeed. I knew there was a Ford special built in NZ by Alan Watson, Auckland, later known as the Ching Special, once sold to Noel Ching, Nelson. He (Noel) later build more of them.
You can read bout them in Graham Vercoe’s ‘Historic Racing Cars of New Zealand’ and in Patrick Harlow’s ‘New Zealand Manufactured cars’. Those cars seem to be just like yours, and if you search online you’ll see that the red and the white ones are in some topics where the Ching is discussed…Peter Colmore-Williams’s company, Sonata Laboratories, run a production of moulded items in glass reinforced plastic, called Epiglass and in this line, beside boats and other stuff, there were some car bodies.
Is there a relation betwenn the Watson\Ching Special and the Sonata? And was it called Sonata or they just produced the bodies for someone?
I’m always intrigued by those specials and the info you find online are seldom trustworthy…
Best regards,
Paul Jaray
