Scion always maintained the stance of promoting creativity through its cars, resulting in introduction of interesting concept cars every year. For this year's SEMA show, Scion rolled out six unique custom vehicles from Cartel, Dynamic, 686, Michael Chang, Jon Sibal and Tatsu. All are highly individualized and these works showcases the potential of customization of Scion models. Three of their models, xB, tC and iQ were tweaked to perfection turning heads at their stand. Without a doubt, the iQ Pit Boss by Cartel adorned the extremest of mods which includes chop top, extra wheel storage space, wireless hot spot and it is even completely controllable using an Apple iPad. Check out the full range of the concept cars after the jump.
