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?

Well, yes, I suppose I implicitly assumed that it would be difficult for Porsche to sell the 960 in the first place given what else they sell at a similar price point.

Your argument borrows from the Ferrari and McLaren strategy, but only one of those manufacturers has a customer base that sleeps easy at night not worrying about depreciation (whether they drive the car or not).
