OK guys, lets get our stories straight.
The 987.1 (2005-2008 Boxster & 2006-2008 Cayman) have an IMS bearing.
In mid-yr 2005, Porsche began using a redesigned IMSB. A 2005 Boxster may have either design depending on the build date. I believe the change over to the new design was approx Mar 2005. The old design is easy to replace, the new design requires the engine halves to be split in order to replace the IMSB.
In 2006, Porsche introduced the M97 engine in the 987 line (the 986 has an M96 engine). The M97 had the new IMSB design introduced in mid-2005. That design stayed in production until the 987.2 was introduced in MY 2009. The 987.2 does not have an IMS or IMSB.
The new design IMSB has a much lower failure rate than the IMSB used from 2000-mid 2005. As usual, there are no solid numbers to go off of, but the consensus is the new design fails at a 1% rate vs the old at 10%.
That's why the IMS lawsuit only includes Boxsters to mid-2005. The new design does not fail enough to be included. Caymans were not part of the lawsuit because they all have the M97 engine.
So if you sweat over a 1% chance of something failing, then get a 987.2. You'll probably have a better chance of a waterpump failure in a 987.1 Cayman than an IMSB.
The only angst on P-9 is from early 2005 Boxster owners who didn't change out their IMSB to Jake's design before theirs shot craps. Or someone whipping up the hysteria who doesn't know the whole story.
Buy a Cayman and enjoy it. I own two 987 Ss and I sleep well at night.
