I think you can still get a new bumper but the price is $546.93 and it will be on a slow boat from Japan, the used one for $350 is a pretty good deal if the condition is good.

I bought a new one when my VX killed a Subaru and it looked great until I bent and scuffed it in Moab last year, so a used one might be been better unless you do not go off road and want the nice new one and have the extra cash for the new bumper.
