I am not trying to stir the pot, but I have never seen anyone be so definitive about the percentages, do you have a source? I am genuinely interested, if there is hard data I would love to see it, it might change my view.

EDIT:
I am trying to figure out the numbers a bit, although there is no public hard data on the issue so it is all speculation.
If we take 164,874 986 Boxsters, and divide by 8 years of sales 97-04. We end up with 20,609 Boxsters sold per year on average, however only years 01-04 are really affected by the IMS issue, so 82,437. However, in the header of Jake Ray's PCA article years 01-05 are noted to be those most affected. So if we use the number given in the top autoblog article, that 27k Boxsters and Caymans where sold in 05/06, and assume half are Boxsters we can add another 13,500. So total estimated cars affected by single Row IMS issue - 95,937. That is just an estimate, however it does support the case of IMS being a higher percentage issue, because in the past people (including myself) often referred to the issue as being out of 200k Boxsters sold, not 95k. The unknown variable is still how many cars actually suffered a failure.
EDIT 2:
Here is a
link to the Class Action lawsuit, mentioned by Jake below. Section II B gives a good idea of the numbers. They had access to PCNA files, so I would assume the numbers are pretty accurate. 4-8% for 2001-2005 (which is in line with the 5% normally speculated on these forums in the past), less than 1% for other years. That does change view significantly, glad I could be a part of the discussion.
