I'm from the E53 forum, thinking about getting an E70...there is only one BMW dealership in town, and the service is horrendous. If you want a loaner it will be $15 a day...and they never return your calls and they always seem to lose your appointment for service when you make one online...just terrible...anyways....getting away from my tangent...I have driven a 645i on loan and i must say...if I was to get rid of my X, and have a crisis, that would be the one...
