That's a very nice ride. I've driven one a few times. I like these along with the AMG Mercedes. I work with a few peeps that have these. Only one has this particular car. I've driven more 7 series.
I don't really care for the i-drive system BUT it is more user friendly than when it first came out...you should have experienced them.
I remember the first time I drove one...the owner wasn't there. I thought WTF !?!?!?!?!?!?....I couldn't even start it and then couldn't get it into gear after I figured out how to start it !!!!
Again...very nice ride man...congrats.
