I would be scared of a low mileage 996 that may not have run enough to show a RMS (non concentric) problem. I'd rather buy a higher mileage car where you know things have held up.

On the old air cooled stuff the seals leak because they are old. Replacing them will fix the leak for another decade +. I have done so on my SC and it cost about $200 for the entire engine. On the 996, if you have the problem with non concentric components, replacing the seal will not fix it, only a new engine will.

I am pretty active in the local club, and have run into a few 996 owners with new engines in their cars. Not many SC, Carrerar or 964 / 993 owners I know needed a factory replacement engine under warranty.
