I have been trying to find the thread online about recent Kuruma Z molding quality going down.. I recall someone posting that they have a weird texture now on a couple recent sets and don't match OEM close anymore.
Could have been just a handful of sets, but with certain vendor reputations I *wouldn't be surprised* if thats why they are so heavily discounted. Not throwing shade at any vendor here in particular as Ive seen it from many... just throwing.. it out there.
