I think you may be overlooking something Guest, and that is that $250,000 cars buyers don't necessarily buy and hold a single car through the product life. As long as you space out the car launches, there will be tons of people who just swap cars when the next hotness shows up. Just like when people go coupe -> convertible -> track-day.

The trick to expansion of a line-up that avoids cannibalization is getting people to just buy them all.

So is there room for a 960? Absolutely. Why not?
