looked after or not, 235,000 is a fair few kms. Saying that, sure, it might be a good engine to put in an old car to make it a bit more modern/better in performance, but alot of people seem to think that 4AGEs are some sort of super race engine. they are not really. It really depends on what you want from the car. eg car use etc....
Really depends on what you plan to do with it. ie; drop it straight into the KE70, rebuild it first etc........
