I don't know. My oldest paid 6k for an 07 Corolla S with manual trans and 125k. It was a trade in at a dealership and in great shape. Seeing it will go at least 300k or more, he will have years to drive it and it looked like new. Yep, we had to go through a lot of trash to find it but they are out there..
Is it the 5-speed? If so, unfortunately don't expect to make the 300K. Been there done that. The transmission has an unsupported 5th gear (i.e. not a bearing on both sides of the gear...its just kind of hanging out there in space. Over time, expect it to get noisy. Mine made it to 260K (which I am told is a high water mark). I did the 5 speed to 6 speed conversion (direct, drop in replacement). As far as the engine goes, yea. They will last.
