Nice choices of cars. Just one thing on the 08+ STI, did you check the drive setting? Make sure it was set on sport mode (there is console near the shifter) that will dramatically change the throttle response.
Don't forget to test drive the Evo X - esp the MR which I think will be a great DD.
I know this is not in your small fun car category, but you might want to look into Jeep SRT8
They are giving these away at the moment. 0-60 in 4.5 sec but mph is out of control.
Good luck!
