DLH559 Yes, this is just an Australian Holden HJ Premier with a Mazda badge - and a tiny rotary engine! I would think a 13B would be thirstier than the original V8 the Holden came with... This has to be one of the strangest exercises of badge-engineering ever! Most Roadpacers were sold to the Japanese government, and then later crushed, but a few have made their way back to Australia and NZ.
