my 07 es350 window fell in the door
 

Im pretty upset my driver side window fell in the door. I took it to lexus they want $600 to fix it thought it was kinda high priced. Googled this make and model and seems this is very common due to the fact the window is being held up with plastic clamps that are molded to the window. A luxury car held with plastic clamps. This should by a defect. I should not have to pay for this. Anyone know what i should do. Right now driving with. No window and is very fustrating.
