I personally think its ricey. They are VERY few two-tone cars i like, most of them bordering on even being called two tone at all. Instead of doing the two-tone and design you can spend your $ on a very nice solid color. Have you ever seen candy paint in person? Beautiful! Go google some candy painted cars.
Your design/color may turn heads, but not always for the right reasons. Where as something like a quality solid color candy will get the attention of just about anyone in a mostly positive manner (depends slightly on the color you go with).
