Wow, such heavy criticism from Porsche-philes can only mean one thing: jealousy. Oh sure, most of the guys and gals on that forum can afford a Viper, but to acknowledge that their mighty Carrera might be smoked by a "brutish" low-tech American car such as the Viper - absurd!
I have never been challenged by any one driving a Porsche, even though Porsches are extremely commonplace here in the Silicon Valley. Moreover, the Porsche owners usually do not acknowledge nor do they tend to show appreciation for any other cars. In comparison, I've had countless Corvette and Mustang/Cobra owners come up to me at the gas station and ask about the car.
Not all Porsche owners are snobs, but some of their posts indicate that they have the same unfounded "superiority complex" as a certain infamous leader that hailed from the same country as their car [actually the 'dictator' was born in Austria].
