Over 200,000 is not really a big thing to worry about. Mine had 307,00 on it when I bought it, never touched it till it had 320,000. Then I rebuilt the engine, not really because it needed it but because the head gasket started to go. I could of just put a head gasket in it and kept running it. The bearings in the low end didn't even show major wear or anything. So just because a car has over 200,000 on it don't mean it is a bad car. Yes on a h23 it is a very bad deal, just look on any prelude forum and they tell you that high milage and h23's don't mix. Besides if it is rebuilt theysay you don't get but about 60K on a rebuild. They are really expensive to rebuild any way. So definetly if you want a prelude then get one with a h22 or get one with the intention to swap in a h22. Just my , based on me and my neighbor having to deal with one.
