It all just seems so strange simply because Scion, at least to me, is the "Afterthought Brand" for Toyota. Everything mainstream gets the swoopy Toyota badge on the hood, everything else gets pushed off to Scion. Maybe it'll work, maybe it won't. My guess is that they're hoping to sell a bunch of tCs after this... Bring the kids in for the FR-S, find out its RWD in an area with snow, send them home with a cheaper tC. Everybody wins.
Also, I agree the FR-S is the bet-looking. Losing the rediculous fog lights from the Toyota, and the plastic thing from the Subaru goes a long, long way to make the car look substantially better. I'm interested to see what the "base" wheels look like. The 17" ones are suggested to be optional, perhaps they'll be pushing these out with 16" steelies?
