personally, I’d rather have an original Factory IMSB that wasn’t “fixed”. There’s been more than a few cases here where a “fixed” IMSB was just a quick patch to unload the car. For the 1999, the incidences for IMSB grenading on the dual row Factory IMSB is less than 3%. No way the “fixed” IMSB are that low when you factor in dishonest owners trying to dump the problem on to the next guy. But good luck to you in your search.

My 18-yr-old original IMSB is going to stay put.

I agree with this, especially after watching the PCA video where Mr. Raby did such a fantastic job explaining the whole IMS situation. Mine is an early build date 4/98, so there is no value in replacing the IMS . And while Dash01 suggests that my absurd suggestion is superceded by market value, it's important to keep in mind that these market value numbers are based on a variety of factors and treat all cars equally effectively taking the brand and other performance factors out of the equation. I'm not trying to glorify the 996 or put it on an unrealistic pedestal, but at the end of the day, it is a Porsche 911, and these cars don't just keep going down in value. You will always find something cheap, or find a "deal" but for the most part you get what you pay for.
