How many have NOT changed IMS bearing on their 1997-2000 Boxster?

[AKnowles]

1999, 2.5L, 72K. I have not changed my IMS bearing since I bought it, but the carfax for my car stated:

08/10/2001 24,665

Transmission removed to complete repair
Washer nozzle(s) replaced
Front wiper blades/refills replaced

A/C system checked
A/C refrigerant recharged
A/C condenser replaced
Intermediate shaft seal replaced
Rear crankshaft oil seal replaced
Oxygen sensor replaced

02/21/2002 29,439

Transmission removed to complete repair
Rear crankshaft oil seal replaced
Intermediate shaft seal replaced
Blower motor replaced/repaired
Recommended maintenance performed
Four tires mounted and balanced
Alignment checked
Two wheel alignment performed
Transmission fluid flushed
Brakes checked
Oil and filter changed

After that it is nothing but routine maintenance. So, If I read between the lines properly, my RMS & IMS were corrected at the 30K mark under warrenty. More or less. When I need a new clutch, I'll have the IMSB replaced as well. I'll just consider it anotjher wear part and be good for another 50K+ miles until my next clutch replacement where I'll just do it again.
