Also...there is a HUGE differece in quality levels from OEM and aftermarket. But also a HUGE difference in price too I replaced my front bumper and impact strip for my
95 e320 wagon earlier this year and the aftermarket are really thin and flexible but it was 1/3 the cost of OEM too. Still looks nice, but the OEM one I took off was 2-3 times thicker and much tougher feeling. Made me have second thoughts.
