Depends on your taste and choice. Scion is a newer design, it's more of a personal coupe with good looks.. It has the TRD supercharge option that should get more sporty. The RSX has a more rakish (wedge) appearance. And it looks more of a racer. Both are good vehicles w/ good names to back them up. I would choose the SCIOn for value/reliability/good looks that are not too agressive looking as the RSX. You can't loose, just how much you're willing to plunk down for one of these babies. have fun.
