The only reason I got my WRX was because that was the closest thing to me having a rally icon (Mitsu-EVO vs Subaru-WRX Sti)...I was about to pick up a 2.5rs back in '99 but rumor had it that the WRX was was gonna be coming to the US...So i waited...finally, rumor became reality and got on the 1st allocation waiting list in Jan '01 and received my car in Mar '01...few months later, the EVO was rumored to be coming to the US, and is now finally here...that was the car that I've always wanted since '97 (EVO IV)...
the two cars are pretty much equal IMHO, but the only thing that i'm weary of is the STi's new engine, where as the EVO has been using the same tried and true 4G63 engine for the past 9 years...
