Yo,
I tried to get a set of RS 1.0 grilles for my Black Cherry TC, but Scion sells them for like $750, per grille (it's limited edition).
I called some folks over at TRDSPARKS.com and they explained that the grilles are VERY expensive b/c they don't want people to buy them and build their own "RS 1.0". That crap sucks cuz a friend of mine has one and I wanted the same grille setup. Anyway, I made my own grille and it looks pretty good. My homeboy and I put it together and it took about 3 hrs. (cutting, measuring, painting, etc.). You could probably still buy the grilles, but I think you can find a better use for $750, ya know!
