Yeah, I did when I did the interior. Progress will probably slow down over the next few weeks due to school and academics.
Why did you named it bruckell considering that its an american brand and the skyline is japanese hirochi or ibishu would be more fitting
Mod is pretty much abondoned although Generic is still somewhat active. Personally, because the car's polyflow is very high and that some bits of the car (especially the 'flipped' interior) has Forza-like edges, it's likely a port that he was doing.
Yeah, its just a forza model that he is slowly unhiding the pieces of in the first page to make people think its getting worked on.
Looks really good so far, but I wouldn't make it too similar to the skyline. Give it your own personal flair, change it, make it better, it doesn't have to be exactly the same. And if I were you, since @NinetyNine!'s Miramar mod will most likely never be finished, you might go ahead and make a Japanese version yourself. But do what you want, don't let me tell you what to do! Great job!
