I bought a Pfeba IS trunk spoiler from a member selling one in the For Sale Parts section. I bought it for $150 + $20 shipping. The condition stated by the seller was to be in "very good condition." I received the spoiler yesterday, which was wrapped in a thin layer of styrofoam packaging

I paid top dollar for this spoiler, but with the scratches put in compliments of UPS, I would say the condition is now only fair - definately not worth what I paid for it. This is all due to crap job of packaging by the seller, and could have been avoided if he had wrapped it in cardboard.
I pm'ed the seller letting him know the problem, and I know he got the message, but he has not responded. I still want to keep the spoiler, and will deal with the scratches, but I would like some of my money refunded (via paypal) for the seller's negligence. Does this seem reasonable? Any advice please?
