All I can report is what I see. What I see is between 10 and 20 percent.

While I respect your expertise as a Porsche mechanic (an expertise I absolutely do not share) I have to ask you to respect mine as a statistician. And I have to say this doesn't make any sense.
I'm not saying it's NOT 10-20 percent; I'm only saying that unless all 200,000 Boxsters are regularly serviced at your shop, you can't possibly have any idea what percentage of the total Boxster population is affected by IMS woes. Yes, perhaps 20% of the Boxsters
you see have IMS failure. But is your clientele a representative sampling? Perhaps you have a reputation as a great IMS bearing expert, so everybody within 100 miles of you who has an IMS failure comes to see you. Then you would be seeing 100% of the problem cars in your area, and every other shop would be seeing 0% of the problem cars. (I'm exaggerating for emphasis.) So if we asked them, the failure rate is 0%, and if we ask you, it's a huge number.
I went to Jim Ellis Porsche last year to ask about an LN install on my '04. They are LN authorized installers. I was basically saying, "Tell me I need to do this and I'll give you $3000 or so to do it." The Service Writer talked with me a long time. He had been there 4.5 years. In that time they had dealt with 5 M96s with failed IMS bearings, and two of them were late model 997s. His words in conclusion? "If I was buying an 03 or newer Boxster right now there's no way on earth I'd have the IMS replaced unless the car was showing signs of needing it."
So your two stories are wildly different. I don't believe either of you is lying or even leaving part of the truth out. I believe neither of you has enough of the story to draw any sort of statistically relevant data.
thanks,
