Found this link around, apparently it's from the ls-rp.net community, they got together this huge modpack and it has some skins with value, others have links that are broken these days.
There's also cars and weapons mods, but I find it interesting for the skins only.
You need to download the mod to see the pictures but it's a fast download and you most likely won't regret it.
Individual skins are under Skiny/ and modpacks in Skinpacki/
