 Can't wait to cross break-in period, this car is born to be driven hard.  Exceptional handling, power to spare, gorgeous interior.  What more can I say, except can't wait to drive the new m5.  My jet black 545 truly gets better the faster and more demanding the driving gets, don't sell yourself short by going with the smaller 525/535.  You will not be sorry with the sport-packaged v8.  I've heard the iDrive was a paiN, but as a first time BMW buyer it is very easy to use.  This car is why driving is so fun, I have no regrets at all, only tons of miles to enjoy. Ya-hoo!!
