Supra MK4 bumper need some pricing info

I've got a MKIV Toyota Supra rear bumper I need to sell. I don't have a clue to as what it's worth because I can't find anywhere selling one to base a price off. It's not in great condition buts it's also not cracked, smashed or split. Just paint scuffs and some small deformation from being stored in a cramped place. It's a original supra bumper.http://ift.tt/2sUqTNk picture of bumper.Not sure if this is really the correct place to post but someone on here just know. via /r/cars http://ift.tt/2tDYs3j
