20% would indeed be a scandal.

But even 2% is truly outrageous given its competition.

Further, we wouldn't even be having this debate if Porsche simply released the data it has or at the very least gave a ball park figure of "to the present we've documented X number". But they haven't put that out which should make you wonder:
If you're sitting on data that would extinguish rampant internet rumors that tarnish your name why would you just continue to sit on said data? I'm guessing its pretty bad.

People have said that these rumors may potentially drive down the price a prospective buyer is willing to pay, but I put that squarely on the foot of Porsche's doorstep. Look at how much trying to bury poor execution or design is costing Toyota by simply failing to acknowledge it. It could well be that a microscopic number of Toyota's (given the millions of cars they produce) are affected by their reported problems but by simply failing to own up to the problem and level with the market, in a timely way, it is now costing them tens of billions. Stupid.
While Toytota's mistake is a safety issue, the mistake, in principle, was the same. Let the public find out about our mistakes on their own dime. Which means the people who are probably in less of a position to shell out such an expense, buyers of second hand cars vs. those with the means to take on new car depreciation, are going to bear the brunt of these repairs. That will certainly shrink the market of prospective buyers in this new economy where people are trimming back on indulgences and taking fewer risks.
