Machan the WRX is 265 BHP standard and the STi is 286 BHP standard ( thats the 7 and 8 as the new STi 9 is 300 BHP as the 'Gentlemans Agreement' is no longer in force ) but the pricing of the STi 7 fluctuates from 4.8 to 5.9 mill...dunno why but it does depending on Mileage,Age,Condition etc etc... Hope that hepled...
