Just wait for white. When I was searching for my s2000 I almost gave in and got a red one instead because the 02s in white with red interior are nearly impossible to find. I'm glad I waited until I found the exact car that I wanted. It took nearly a year to find but it was worth it. If I would have gotten red, I would have regretted it every time I would have seen a white s2000 on the road.
Here's a pic of my car in the garage next to my dad's 69 Camaro. I think white sports cars look great and really stand out because they are fairly uncommon. I've always loved white Camaros with orange stripes, but I would probably get either CGM or IBM because I already have a white car.
