I didn't ever have a WRX, but I have always thought they were nice cars. Reasons to go from it to an EVO...well in my opinion the top reason would be handling, the Evo just does period then you get coilovers for it and damn...they are similar cars though EVO, STi, WRX...they are all similar, I guess the modability of the 4g63 is really nice too...but I'm coming from an Eclipse so it really isn't any change.
