What is the original color? You will kill the value by changing the color. There's nothing nastier to me than popping the hood of the car and the engine bay is a different color than the body. I wouldn't go with flakes. If you want to do something crazy, go with Kandy or pearl or something. That is if you don't like the factory color. I'm partial to black 190E's, or silver. Those colors fit the car really well.
