Obviously you didn't read, you are thinking of the oz-spec, which were completely different to the jap HR31. Jap HR31, as racsov said, had IRS, ABS, HICAS, AutoSpoiler, and lots of other features. The one sold here lacked all of that, and was targetted at the commodore and falcon sort of range, not the more upperclass that it would have been if it included the sort of things the japs had.
