Yes, the demand is there because it is "limited" and "special". If you start building thousands of this car, then it will cannibalise on the rest of the 911 sales, which likely have much higher profit margin anyway.

Not to mention the Porsche Motorsport image, that offering a "convertible GT3 with rear seats" would seriously dilute the GT-brand and I hope they will never ever do this.

That is your opinion. The rear seats don't add that much weight and are part of the DNA of the 911. Allowing bland specs of GT cars do much more damage for the image of GT cars IMHO...

Do you think the SA Aperta or 16M or LaF spider dilutes Ferrari brand?
Do you think the Boxster spider dilutes Porsche?
Do you think adding a cockpit to F1 or going back to antique manual transmission makes them more manly? Smiley

Sorry but there is a huge untapped niche by Porsche in a whole GT line that they could sell at a premium price and with more margin than the regular 911, especially since the new GT engine is much cheaper to build than the old one Smiley Heck they could even use the extra money to actually develop real cool tech like carbon tubs and weight saving measure instead of throwing money after bad useless hybrid technology.
