There is a car thats red/white and it has the door handles shaved. That looks cool!!!!!
Suicide doors: I think that would be cool but it would be hard since our doors are so rounded at the back.
Removing the rear pilars can be done but not recommended. They are a support for the roof and in roll overs.
Yes it would look sweet but I don't think it is possible and will still think that until I see one.
