Hehe, somebody has the same idea as me. I've had the current BMW model's sound as my ringtone from the time that I bought my first s60/symbian phone that could play mp3 ringtones. Currently I have the 130i revving up pulled from the www.bmw.com
mediacenter. It made for pretty hilarious time while around at the BMW dealers over here, when everybody started wondering if somebody had started a car inside the the dealership and was revving one up, since it includes the ignition sounds too, hehe.
