Sounds like it's going to be one mean looking car!
Mine is white as well and I love it! Be prepared to get dust/black specs on your car and these can be easily seen. Dark colored ones get swirls, light colored ones get the black specs. Nothing is perfect.
Agree with RC3. Just have it wrapped. Check this out:

You can mix it up. Since car is matte, you might want to go gloss black grills, gloss window trims, and gloss rims. Or just do matte for everything.
