Dude, if I want to make it looks smooth, I can, as you can see it here.
I'm not talking about me, I know how to do, I'm not a PRO but I have the basic knowledge, that's not the point, I just said LFS cars sucks, as RB4, for example.
I know you asked for Bose, but as I was bored I had to do something...
Just a preview, if you like it I can do the size you want and the XRT aswell.
(Don't blame me for the reflections, blame LFS for low-poly cars)
