...the SPACE SHUTTLE. Nick, this is one of the most ridiculous posts you ever made, honestly. Why would someone compare a tuned version of a car to the stock version?
It doesn't make sense to me at all, especially since most of Gemballa's extreme power toys aren't even streetlegal in Germany, giving you a pretty good hint about those models.
These are cars to impress people (like you for example... ) by using extreme power figures and impressive specs and performance figures.

And if you REALLY want to be impressed, you better pay SPORTEC a visit, they have a 800+ HP 997 Turbo (based on the 997 body and the "old" 996 Turbo engine) available which puts the Gemballa version to shame.
