Could have been me, if it was a GT. A non-forum buddy of mine in Garland has a yellow Sport. My dealer called tonight to see if I'd picked up my plates (got my car July 15th, still no plates which is actually cool), said that he sold another yellow car last night.
Last night I finally saw another RX-8 on the road, silver on Independence/Park in Plano. Flicked my lights, not sure if he saw me, although Lightning Yellow is hard to miss.
I LOVE my car! Enjoy yours!
