I think that the Porsche line is a little too wide considering the Cayman is on top of the 911 in terms of performance. What about...
The Cayman melds with the 911 and the 911 is once again a $70-90K car. The 911 was once very price competitive with the Corvette, and this would bring it back.
The 928 is, as it once was, the "luxury touring" flagship of the Porsche line.
The 911 turbo returns as a RWD ripper. The original 1976 version had luxury goods, yes, but was still raw and all about performance.
