Hi, I was trying to find this car mod on forums for a while. The mod I remember seeing was a model based off the Ibishu 200rx, but had the body of an Nissan Skyline R32, and a lot of configurations given. I apologize for the lack of info, as to I don't really know anything else to it beside this info.
99's 90's Ibishu Miramar, the one you were talking about, is canceled due to someone leaking the mod (I think)
The mod was finished, but never publicly released, although there is a beta version with no interior floating around the forums.
