The demise of the IMS has been greatly exaggerated.

This is just my opinion, of course, but because I'm a DIY-er, I do a lot of reading, and I research everything I read. Sure, there are lots of "experts" who'll tell you one thing or another (for instance; this week we've heard on this very forum, from someone who has an "expert Porsche Technician" who says you can't track a Boxster without losing the motor. This is demonstrably false) These "Experts" come with varying degrees of experience and qualifications, and you need to remember that, when assigning a value to their opinions. You also need to understand the agendas which sometimes lie behind their statements. DO NOT DISCOUNT THE AGENDA of pride; Those who have spent a LOT of money for an IMS Solution to gain "peace of mind" are sometimes (not always) threatened by those who think that might be a little overboard, or even foolish, on a car that isn't worth $10k in resale.

I replaced my IMS bearing when I did the clutch. I honestly wish I hadn't. with 147k miles on mine, it was still PERFECT. But as another member commented: once removed, it's junk. But I took out a KNOWN-TO-BE-GOOD bearing and replaced with a giant question-mark. (Yes, there are some instances where the replaced IMS, and even the "solution" have failed)

MY daughter bought an '08 Subaru Legacy last year, with 80k miles. After 9 months of driving, she lost a head-gasket and overheated. The damage was catastrophic to the motor: chunked a cylinder. She put a USED motor in it, to the tune of $6k. Yup: a USED motor couldn't be had for less than $3500. Turns-out this is incredibly common on the NJ25 motor. My point? ALL USED CARS HAVE A CERTAIN RISK OF FAILURE. And most used cars have COMMON failures.

Ultimately, you need to decide what the car is for? IS this for FUN? Then forget about the IMS and go have fun. Elsewhere on this forum is the GREAT advice: Drive More, Worry Less".
Is this car for INVESTMENT? then you picked the wrong car. HARD Pass on it. The Boxster is not an investment car.
If the car has some sort of sentimental value to you, or represents a "bucket-list", or whatever, and you plan to keep it forever, and pass-on to posterity, then YES, do the IMSB. This is the only instance in which I think it makes sense.

Again: just my opinion, based on my own experience and all the reading / investigation / research that I've done.
