A new 2003 Toyota Tacoma front bumper costs between $100 and $200, depending on how badly damaged your current bumper is.
If you only need the bumper, it should only cost $100-$110. If the damage is extensive and you need the bumper, bumper cover, and valance, expect prices to be closer to $200.
Before paying for repairs yourself, always remember to double-check whether or not your insurance might cover the costs. If not, it might be time to consider more extensive coverage.
