Imported default GTA SA car looks different in Game after exported from blender.

Here is the original Admiral in GTA SA:

Here is a Admiral that I just imported & exported without modifications. Default settings on both import/export.

Edges are sharp and not smooth as in the original model.

I tired many solutions and nothing worked as expected to make the normals fixed. Is there any way to fix this and make the car look the same after export?

is custom normal map checked & edge sharp disabled?

@NaufalFajri with custom normals it looks better in blender but the same in game after export, with edge sharp disabled it's too smooth and edges are almost not visible.
