 This is the fifth MB I've owned, and this one's the best. It handles beautifully, and is a delight to drive.  But, the GPS has me screaming! It takes me the long way, and through neighborhoods no one should drive this car through. I now print maps from my computer before I leave home, and don't rely on the one in my car. Too bad.  Satellite reception for Sirius is spotty, and not my first choice. I prefer the XM system.  Oh well...  But I still love this car. Thanks Mercedes! You've done it again.
