There are probably some owners out there who do not participate in internet forums and take their car to the dealership for maintenance. I can imagine that such people can just drive their cars happily with no worry, or even knowledge of what an IMS bearing is. I don't think that Porsche officially recommends any replacement of the IMS bearing.
IMHO, buying an '03 or '04, have a good 986 knowledgeable mechanic do your PPI to check for signs of a problem. After you buy a car, have the IMS bearing replaced at your convenience if it has not been done. If you find that driving on an original or unknown IMS detracts from your enjoyment, get it done immediately upon purchase.
