If you look at the engine pic of the 2000 CS you can see some surfaces that are the same color as the fender.
It can be difficult to judge colors off the web. I know full-well that my remote computer monitor displays a different hue than my laptop screen. White is very hard to color match, only way to be sure would be by seeing it in person.
Interesting car, though. Interior redone, not quite 100% correct but nicely finished. Washer bottle not correct but it works. Heater fan is a later unit. Gotta lose the rubber ducky antenna... But it has an original rearview mirror and those are unobtanium, wood looks great, engine bay looks sorted, broken side indicator...that might be tough to locate and it is a bear to install (those headlight fixtures are cool, but difficult to work on)
I'm just pleased to see another 2000CS out there.
