The name of that color was Impulse Red. It was only available on 2003 SR5's. There was aldo Imperial Jade Mica (green), which was only available on the 2003. They were both uncommon colors.
I've never seen one either.....kinda different with the cladding. Not my style, but might look cool with different wheels, lift, and some big meats. Might like really cool actually....
