I don't really think it matters what your Boxster is worth. Unless the wheels are literraly falling off then most likely you are planning to keep it long term. If keeping an older Boxster is your plan then you are going to end up spending a fair amount to keep it running as a Porsche was intended to be. This is true of all Porsches from rare to common. Point is there's no point in owning one of these cars if its all busted up from outstanding repairs. If you are going to make that committment then there's no logical reason to put off the IMS upgrade. Sure you can wait until the clutch needs replacing but I think this is a dumb move. At most you'll save a few hundred bucks getting a few extra years on that clutch while gambling that if it goes against you it will cost you thousands. Good luck selling a Boxster with no engine.

btw, my dual row IMS was in PERFECT condition when it was extracted.
Until they come up with CAT scans for car engines you can either stress out about possibly being one of the unlucky ones or you can get the upgrade.
No brainer.
