I see your list of vehicles includes 07 STi; If you are buying used i would look at 06 and below for the STi, just because the new emission laws caused some ringland and acceleration stumble issues in some 07+ STi's. If you can afford it i would look for inventory 09's since it is the end of the year and i am sure you could get a 09 for sub 33K... or better!f The trans in STi's are one of their strong suits from what i have read.
