Well, it is a personal preferance thing...
Most friends who are not car nuts are puzzled as to why WRX owners want more power? It already has 227hp and does 0-100 in ard 6 sec. Yet most owners want up,dp,xzos,bc,fmic,ecu etc etc... to make it even faster.....
So I usually hear... Damm you spending 2Gs more to make it even faster? You crazy?
It all comes down to personal preferance...
