2007 E92 BMW 335i
Accidentaly I found out an awesome feature about my Seville. When turning the ignition, you don't have to hold the key until the engine starts up. Just turn the key until it starts to crank, then let go and it keeps cranking until the engine fires up without you having to keep holding the key. I remember reading up about how a BMW 540i could do this, so I tried it on my car, and low and behold it works.
