There will be no 05 Cobra. It doesn't come out until 06.
Changes for the 05 STi are an improved interior, wider wheels (17x8 with a new lug pattern 5x114.3 instead of the old 17.7.5 and 5x100), some revised exterior trim, a new "Crystal Gray" color paint, you can get fog lamps as an option, a better security system as an option, and the premium stereo system is now standard.
In order to get rid of the big wing, they will have to swap out the entire trunk lid with someone with a WRX of the same color (with or without the WRX's small spoiler). There are usual a lot of WRX owners (not me) lining up to do this, so your dealer will simply ask one of his other customers.
Thus far, STi's have proven to be very reliable, with only minor complaints (especially considering the vehicle's performance).

So congrats! What color scheme have you decided on? I'm a big fan of WRB (blue) with silver myself
