Update: X3 warms up pretty fast also. (Still getting used to no coolant temp gauge but oil temp gauge instead). Only thing is that my MB adjusted the fan speed automatically on "auto" climate control setting, whereas the X3 does not appear to do that and operates at whatever speed you set it to, even in "auto" setting. Note to self: Do some searching and RTFM to see if there are any hints about it .
