I think my question is valid as originally stated. The purpose of the car's design, not the car's release, was to create something unique. In doing that it seems to have failed for the reasons stated.

I'm not sure what part of that assertion you're taking issue with? Who cares about my purpose, I am speaking from a design critique perspective, not a marketing perspective.

Sure the wheel is not specific to the Turbo, but the Turbo itself is not a limited edition car. Porsche's design division is supposedly a seperate corporate entity than the auto division, yes? Their chief concern should be the purity of the design ethos. Either they completely overlooked this (unlikely), or the bean counters overruled them. In the end the product's uniqueness has been compromised.
