I found the initial kit that is found in the header image of this site to be a little extreme. Scion has definitely taken a step back from this approach and really went quite the opposite, almost a little bit too much. Wish there was something just a bit more aggressive on the front end bumper.
I don't know how aggressive a little car can look That said, the silver/white IQ on the left of the header looks pretty good to me - I like the way it looks.
It would be nice though if there were different body kit options - front lip, side skirts, etc. that could be added on as options. I think full kits will be available once the car is out for a little bit and parts start getting made.
Scion should play the market well and sell lots and I am sure we will see a ton of after market front bumpers / skirts / rear bumpers. If we don't see higher sales figures or demands, don't expect anything to change the look unless custom.
