If a salvage yard does not have any used bumpers that fit a buyer's specifications, there are several websites that sell them as well. UNeedAPart is one example of a business that searches its own database and nationwide salvage yards to build an online catalog of used bumpers.
A-Abco Recycled Auto Parts is another business that sells used bumpers online. Unlike UNeedAPart, A-Abco Recycled Auto Parts has an online catalog covering its own warehouse instead of searching for bumpers in salvage yards. A-Abco Recycled Auto Parts also ships bumpers to buyers' doorsteps.
EBay and Craigslist have used car bumpers as well, though it may be necessary to look into the seller's reputation before making a purchase on eBay. When buying a bumper on Craigslist, it is possible to take a look at the bumper in person before committing to a purchase. This has the same benefit as going to a local salvage yard to find a bumper there.
EBay does recommend researching local laws before buying a new bumper. For example, in some areas, new bumpers have to be about the same size as the manufacturer's original bumper. EBay also suggests considering that a new bumper may not work as well during an accident as the original.
