Actually, it could be the Spa Yellow; the picture to me looks like it just picked up a lot of the "pearl coat", and that is what is showing.
ICBW, but, when I was in Dallas, I saw someone's Spa Yellow NSX next to someone that had repainted their NSX (Sorry about missing names, I'm terrible with that).
Anyway, they were both yellow, but there was a big difference between the pearl coat on the Spa Yellow vs. the repaint. To be honest it's different, but I kinda liked the repaint more (it's just a subjective thing).
Maybe???
