Front I assume, it's hard to say if you can replace it with a second-hand one then just get sprayed about £200_400, I trashed the rear of my Mazda it cost £350 cash to fix
Look on eBay and find a wing in the right colour which will cost you somewhere between about £60-100. They are relatively easy to fit yourself. If you want a link to my videos showing you how to remove a wing and put a new one on let me know.
