I just found a couple of amazing things out about my BMW. First when the turn signal is turned on there are lights on the side of the car that light up
. And with the speedo if you hold down the reset switch and then turn the starter to position #1 (radio on only) the milage and tripometer will go away and be replaced with a series of "tests" 1-15; if you hold down the reset button on # 15 until beside it, it displays "LvOff" you can use your speedo to digitally display a bunch of different things (like RPM, feul, speed in km/h ect.). I thought that was interesting.
