Looks like that has a 2.5L VM Motori 4 cylinder engine... a HR492 (4 cylinders with 92mm bore) also know as a 425OHV.
That engine is not as desirable as pretty much any other Toyota deisel. It most likely has an H55 trans in it, and I beleive the input shaft of of the H55 behind a HR492 is the same that is needed for a 1HZ motor....so if the body is completely rust free and everything besides the motor is in good shape I would be looking at it with the intent of swapping in a 1HZ down the road.
That said, at that asking price, you can get a a rather low mileage JDM BJ73/4 with a 1HZ already installed...if you don't mind right hand drive of course.
