Actually, I had to get used to not starting the 911 like EVERY other car I had previously started. Ever since I was a boy, I have started a car by: pressing the gas then turning the key, or depress the gas slightly while turning the key, or a combination of both.

My Porsche salesman told me that I was not to do that when starting the 911. Just push in the clutch and turn the key. Car starts perfectly every time.
