The IMS can be fixed with an aftermarket upgrade (which I did to my 3.4). If you take some steps, you can make older Caymans pretty reliable (as many have pointed out, I'm not sure there are a lot of car brands out there that NEVER have issues).

As for post-2009 Caymans with DFI (and no IMS), the only issues I've heard of so far are some reports of high pressure fuel pump issues, which are not catastrophic and pretty easy to fix. I have yet to hear of one of the new engines failing catastrophically - keep in mind that the Cayman, Boxster, 911, Turbo, GT3, etc. are all variants of the same engine, so they were built pretty robustly.

As for the general theme of this thread, keep in mind that it only takes one dissatisfied owner to make a big stink and blow the problem out of proportion - you don't hear from the thousands and thousands of owners who have no issues.

I think one of the bigger issues is that many higher performance car makes have their problems. BMW engines in the 90's were notorious for problems that BMW fixed at the dealer. I came across a few 740's that had dealer installed replacement engines because of oil sludging and these were out of warranty. Having an $70k car's engine fail for whatever the reason is a concern. Especially one with the tradition of Porsche.
