I just hit the 50k mileage mark on my 2004 X and it seems that it's falling apart. I've had basically no issues until this point. Now my window motors are real sluggish up front and look like they need to be replaced. I have a wierd noise coming from one of my drive belts. My bumper has mysteriously lost some screws and now rattles. I just replaced my front brakes and they still make tons of noise. And now i'm only getting about 230-250miles to the tank.

Other then just bitching, i would like to know if this is a common thing for the other X owners. Is there a magic number where i should start saving to fix things?
