Legitimately what are gonna be your options once(if) this goes live? Pricey as they are they might still manage to undercut the rare unique parts by even a little bit. Plus OE will ensure that the remaining Skylines that haven't been tracked, drifted or riced stay in as close to mint condition as possible. Also the option to convert a modified vehicle you buy from someone else back to stock anyone?? If they are above your budget, you probably aren't the right person to be owning a 20 year old car, and a Skyline to boot. Obviously value is different to certain people, if you intend to prep your car for the track you might go with cheaper options while someone who intends to keep their Skyline as a more show style car will pay top dollar.
