A new 2015 Dodge Charger front bumper will cost you about $550 for the part alone. If you take it to a mechanic to install it, you can expect that to add about $250 to $300 to the total bill.
Depending on the extent of the damage, you could get away with just putting a bumper cover on instead of getting an entirely new bumper. That option is much cheaper and usually costs between $250 to $350. Plus, bumper covers are much easier to mount and can be done at home in your garage with a little determination.
