If I painted my Z a different color, it would look silly to leave the engine bay as Pearl White. To get the engine bay painted costs mad cash. That would be one reason I'd just get it repainted Pearl White. I'd prefer to get it in either Cobalt Green or maybe Black but I just don't see myself having the cash to get it done right. Typically how much extra is it to get the engine bay painted? As for color schemes in the engine, I have a lot of red parts from my last Z but it doesn't work too well with white.
