It wasn't me, but I was driving my NSX-T with the roof off up Highway 1 (around Santa Monica) when a red NSX passed me. It was red with an all black top, so I figure it was an older model (do they even do the duotone anymore?).
It was a funny site as I hadn't seen another NSX from inside my NSX before, but one I suspect I'll duplicate many times over the life of the car (I've only had mine for a couple of weeks). Anyway, just thought I'd mention it.
