This logic reminds me of the reliability rankings that put Porsches near the top -- except for the Cayenne. Why? Because that's the only car that seems to be be driven daily. Similarly, the age of the car is not really a good barometer for bad design. As we see the prices of these cars falling fast, the new owners will start ramping up the mileage at a rate not seen in the first 10 years.
I predict many Boxster/Carrera owners who will not endure the expense of a bumped up clutch/ims/rms job because the added costs don't fit within their budgets, will see a markedly different rate of IMS failures than those who owned during the first 10 years -- cars sold
well before they reached 100K miles. I also suspect very strongly, that 2005-2008 cars that have their clutches replaced without ever addressing the IMS, even if you remove one of the seals to allow for splash lubrication, will also see significantly higher failure rates than those owners saw in the their first 10 years of ownership.
Point is as mileage goes higher, the flawe in this design will become obvious, particularly how there was/is no "plan B" for out-of-warranty 2005-2008 cars that require the extremely expensive hassle of splitting open the engine. Porsche knows full well that a sealed bearing will not last indefinitely.
