A few owners have contacted me, asking to include the Boxster in the reliability survey conducted at TrueDelta.com. The key question: how common are IMS failures? In response, I've made getting the Boxster into the survey a top priority.
Here's how the research works: an email goes out once a month. If you have a repair, report it. If there have been no repairs, just report an approximate odometer reading at the end of the quarter--takes about 20-30 seconds four times a year.
We promptly update results quarterly, to closely track cars as they age.
Models are included in the survey once 25 owners sign up. Currently the 2000, 2005, and 2007 are each about halfway, and other years aren't far behind.
To encourage participation, free access to all results, not just those for the Boxster, is provided to everyone who signs up to participate.
