My dad's AE111 GLi has more than 200k on the odo and so far he hasn't reported any major problems. I drove it a few months ago and aside from minor engine vibrations I didn't notice anything out of the ordinary. He religiously follows the casa maintenance schedule though.
One common problem of that car is that 'lutang effect' experienced during high speeds. Because of the vehicle's relatively high front ground clearance, there is too much lift once you go faster. You can somehow feel like driving on the clouds.
One solution to this problem is to replace the stock springs with JDM Levin ones. The front should drop by around an inch, but better high-speed stability and feedback are guaranteed. :D
