What Mods to a donor will transfer to the Goblin?

Yeah... I've heard several people from the Goblin world and from the Cobalt SS world saying they can't believe I am going to use this car, etc., etc.

I am not going to do anything that costs me any money on the body or interior (except the shift boot, because it will transfer to the Goblin. And I will likely have the windows tinted because I don't like not having tinted windows...). I don't mind putting in some time to make it look half decent because I am planning on driving it for around a year. The headlights were so bad, the light coming out of them was so diffused it barely lit up the driveway. I leave every morning before the sun comes up so it is important that I be able to see the road.
