I dont know the exact size but there are 6 Torx under the carpet and behind the seats that have to be removed to get to the engine. Nice if you are not doing it yourself. That was a real problem for me, at 75k car I could not even look under the hood without taking apart the interior.

Ridiculous. Considering how "user friendly" (for Porsche) the 996 was IMO. I guess they figure people paying that much for a ride aren't touching the engine, plus it makes justifying a 130/hr rate plausible.
