Put it to her this way, the Boxster come two ways. One way allows you to replace the IMS when the clutch needs replacing. One day job. Then you're good to go for years and years.
The other Boxster (point out that this isn't the one you bought) comes with a free IMS (the one it came with from zee Germans) and the replacement IMS bearing that will cost you $10K when you have to split open the engine, along with a whole slew of "while you're in there" costs. If you postpone spending the $10K on IMS bearing #2 (who wouldn't?), and it fails, you'll need a whole new engine which will cost more than car is worth.
So which was the better choice me lady?
Think of it this way, the IMS bearing is part of the clutch job. It's a big expense but bumping it up early gives you the utility of a new clutch (your $$$$ at work) and safeguards your engine if your bearing is a wobbler. No bearing lasts forever, it should be refreshed with a new one or even an better one at a regular interval. Leaving it in there indefinitely is aksing for trouble and contradicts the laws of simple bearing design.
In addition you should mind the coolant system -- its an ecosytem of watermpump, coolant tank, the most recent coolant cap replaced each time you flush the coolant system with the factory pink koolaide. Use an excellent oil with high engine-saving ZDDP, like Motul x8100 5w40. And if you want some peace of mind, get an oil analysis from Blackstone labs to see if the previous owner was doing you in any favors.
