update: Took the car into BMW and they said $2,300 to fix
to fix the rear bumper only, it says 4 hours of labor, 2.6 of paint, and 3.1 hours to replace RT Guide PN 5112717.
7.1 hours @ 45/hr is 319.00 to repair damaged bumper(not replace).
painting to fix old bumper is 2.6 hours paint + 1 hour clearcoat = 3.6 hours @ 45 hour = 162 to paint.
A 135i rear bumper kit from dan is ~550 without paint. Not sure how much it costs to paint an entire bumper.
gonna have to crunch some more numbers to see if I should just go ahead and replace the bumper vs getting it fixed. I would want to DIY the rear bumper but I doubt my parents would let me also since they have to fix my rear quarter panel which got most of the damage(the rest of the $$$)
