finding one without a rear spoiler is important, but if you want an SE model, it will be hard.
A little timing chain rattle is gonna be heard on ANY 100k mile KA unless the timing chain has been replaced. and even some that have had it replaced still do. (mine for example.. they didn't remove the guides.) A LOT though is bad.
Look for rust on the strut towers, and on the frame, and on the trunk if you see the spoiler.
The washer nozzel on the top of the car tend to leak water as well. make sure it's really well sealed up.
if you look at 89-90 models, beware of leaky injectors.. you will see stains on the valve cover if they leak.
Rough stumbling idle is another one of the KA's common problems when they get a ton of miles on them. Not necessarily a bad thing, but does give you something to haggle with. usually can be fixed with some Carb cleaner down the IAA valve hose.
Notchy transmissions seem to be a problem w/ high miles. especially 3rd gear.
My advice is to think about anything you are gonna mod on the car eventually.. then think about all the things that WERE NOT included on that list. Make sure everything thats NOT on the list is in acceptable shape with the car.
