Sounds nice. As you know I've driven 535d, its great car and fast for a diesel, almost as fast as 545i. Maybe you change to 335d when it comes?
I didnt know interlagos existed for regular bimmers. and the rims, why change? I like the ones that comes with the sportpackage.
Great do hear your father getting better. A lot is happening for you Tycoon, two new babies in a short time
