Most cars in Aus with a crook motor are either scrapped or a wrecker or Japanese import used engine is fitted.
Both reconditioned or "remanufactured" (a label to justify a higher price) engines are simply too expensive even in short block form unless for a vintage/racer or classic car where the car is worth $30K+
We have half a dozen high volume workshops locally who bung in either wrecker used or used Japanese import engines .....otherwise such cars would be economic wrecks.
