I don't like desertfox' story for two reasons:
A) It shows an attitude that continously gets HUMMER owners in trouble. Nuff said... you guys know what I'm talking about.
B) The quoted mpg-comparison between pretty much all (current) Porsche models and an H2 is plainly wrong (assuming that he is not talking about the Porsche Cayenne SUV Turbo version, which is - to my understanding - not a real Porsche, and maybe that is the only P-car which comes closely to the fuel consumption of an H2... but only "closely").
The flat-6 engine of a Porsche (e.g. Carrera or Boxster) is highly prominent for its great fuel efficiency (considering its power output). It is a small modern engine, which has been continuously improved for almost 50 years now. So don't talk BS about P-cars, when you lack the ability to really compare.
That's also the main reason why I picked the H3 over the H2.
How I know all that stuff about P-cars (which aren't exotics in Germany at all, but H3s are!)?... Picture attached!
