I personally dislike all the electronic doodads and gizmos in cars these days, so for me, the simple interior of the WRX/STi is a huge plus and was actually a selling point.
I traded my 06 WRX in on a 2011 Charger R/T .. because in my head, I thought that new fancy interior was going to be great .. and 8 months later I traded it in for another WRX.
I found I hated heated seats and steering wheels, the EVIC display was annoying, and the climate control would not even allow me to simply open the vents to let outside air in.
Now I know that I want less tech in cars. Maybe I'm a control freak .. I dunno.
