you can edit your post (there's a button on the top right, if i remember correctly, that says "edit"), so you don't have to post twice to say what you mean
about a sport tc - i think it would lift up the price even more, and then all of the sudden the scion's idea to have lower prices then others on the market will be lost - it'd probably go up at least couple of thou, making a "sport-tc" close to lower price hondas and acuras etc... so i think the only way you can make your tc "sport" is to put a supercharger or smth like on it
you can safely bet that scion will not offer different trim levels of any of its cars. its the main reason why our prices are what they are. the more trim levels (EX, LX, S, etc...) that need produced, the higher the cost of production, the higher the retail price. a monospec vehicle is one of the scion fundamentals.
