there expensive where ever to be honest... second hand will be best, will take a while to find, but other wise- fake one (avoid crappy fibreglass ones) will be about £500 probably....
exactly, and why are bumpers usually made out of plastic? cos there something which often gets hit, and plastic is alot stronger than fibreglass and doesnt crack or anything when hit, just scrapes slightly.
every single bodykitted car i see, which is fibreglass, is cracked unless its recently done.
