People happily pay more than that for a set of comp cxn so I dont see it as excessive, try finding another new set.
If a 500/3dr owner has a nice show car and tatty wheels Im sure they would pay it if they want to car to remain original rather than run a skimmed refurbed set as the Ford badge in the centre often gets lost in the skim, and the laquer always seems to cloud over quicker on the refurbed ones
Would I pay it - no, but I am tight.
