Hey, maybe what we need to use here is a "sarcasm alert" before we say things like
Pontiac-inspired design
. I agree there are design elements the 996 has in common with Pontiacs and Toyotas.
The performance of the new 996 may be phenomenal. The attractiveness of Butzi's 901 design through the 993 was due to the curves. The roundness implies "This is a car that likes to turn!"
The new design is more akin to a bullet - long and sleek.
The existence of the 993, and the 959 to some degree, seems to affirm the idea that the 901 design could be updated without losing its essence.
Irrespective of any actual performance (I'm sure the new can run rings around the old) the old design just looks more fun. This is of course my own opinion. Your opinions and reaction may vary.
