Look for a better car IMHO. Either go for the new WRX or go for a muscle car. I dont know what your priorities are but if youre only looking at 1/4 and 0-60 times, then you need some american muscle. Get a used Trans Am with WS6 suspension. That stuff kicks major ass. Youll be killing RSs and WRXs stock and then just spend about 3k for a supercharger thatll boost you to 550 or more horses. But its your choice, I personally dont like how the celica looks...at all. It doesnt grow on me one bit the way the WRX does.
OR! I have an even better idea. Get a 92 or 94 Corvette (or any year of the C4)! Yes! That stuff is fast and pimp at the same time. Also they are DIRT CHEAP!! I've seen them (in excellent condition) for under 15k!! I wish my parents would let me trade in my Subaru for one. Those things are bad ass.
