KE55's were built in Oz by AMI. KE30's in Japan. Tho some of the last KE30's during the change over were built in Oz. Like my KE30 (one of the last ones, made in the last month).
There is only one KE55 that was ever imported into Oz and that was the KE55p (Liftback) otherwise known as a KE50. (tho its not, its more like an update KE50 just like the KE55 is an update KE30.
