I'd say if the white levels are clipped, that's by definition not properly exposed. What's underexposed about the photo in question? Do you think the shaded side of the car should be brighter?

How is a ND filter going to help?
http://en.wikipedia.org/wiki/Graduated_ND_filter
It's hard shooting white objects on a bright sunny day because if you expose for the sky then the car is too bright. If you expose for the car, the sky is too dark. With the ND filter, you can darken the sky a bit and this will help you expose for the car. I don't know if I explained that well, but hope that makes sense.

You didn't explain it well because an ND filter wouldn't work if you darken the sky.
It would make more sense to just edit the pic in photoshop. Adjust exposure of the white car and leave everything else alone.
Unless you are trying to get a slower shutter with a certain apperature is when you would stack nd filters.

How are you going to "adjust the exposure" of the white car if the highlights are blown? You can't recover pixels out of nowhere.

hm, i never knew such things as graduated ND filters exist. it'd be even cooler if they had circular graduated neutral density filters rather than awkward square ones that don't fit on lenses? (or do they have them? O_O)
anyway, i think what jarod was getting at is that let's say that the proper shutter speed to expose the sky would be 1/60, but then that'd severely overexpose the car. by putting on one of these nifty graduated nd filters (upside down where the tinted side would be on the bottom), i'm guessing that way, the 1/60 wouldn't overexpose the car anymore? amirite?
