I would strongly recommend that you stay away from that car. If it was a 2zz (GT-S) it would be a different story but, the 1zz is something that I wouldn't buy especially rebuilt. If you decide to consider it definitely take a good test drive in it to listen to the motor, common issues are valves, burning oil, etc... I have had 2 1zz powered cars and the only way I was able to make it reliable was by swapping in a 2zz.
