After some 14 hours of work, Finally Got the car ingame, Sadly M2Mod4 welds vertices that are in very close proximity to each other, which basically broke the physical smoothing groups I had set up, which took me about 9 hours total to set it all up, it was all a waste , In the images it's not very noticable, but ingame, there are ugly visual deformations where the Edges taper off for car panels. Anyway Enjoy...
I'll put up a video eventually when I get the mounting point in.
