I agree with the bugs being fixed after the first year...I had this problem with my IS3. I got the IS the first time it showed here(01).
Things they did in 02/03 and not 01:
Armrest
Full leather
NAV
Black chrome taillights for dark cars ( I have black so I upgraded)
Autodimming mirror, with temp and that sh!t
LTuned package
5 speed
New colors
Sportsdesign package
Just little things basically, but who knows what they can add/take off the STi next year.
I know I am going to wait a year for a couple reasons, and this is one minor reason. I dont mind waiting another year, just to see what others do to the car, and to wait for companies to make things for the car ie bodykits, perf stuff, etc.
