I just test drove an IS250 AWD and tonight an IS350. IMO...the 250 is slow....the 350 however, was fast as hell. I currently have a 03 CLK500 which is going back in January. My dilema is that I live in Jersey and have to deal with the crappy winter weather. When I bought the Benz...I had to throw on snow tires to get around. I hate to have to change tires every season....Do I say screw the weather and go for a IS350 or should I consider a 330xi. I am reaaaaaaaaalllllllly leaning towards the IS....but could some advice. Thanks!!!
