I traded in my 2010 WRX base for a 2010 STi SE.
just to keep it short, it was WELL worth it.
Paid $24,9 for the WRX, traded it in for $23,5
Paid $32,2.. for the STi SE. (In addition to getting my OEM STi HID headlights on the WRX swapped to the STi SE, them uninstalling all mods on the WRX and installing all my OEM parts.)
Im more than happy with my decision, even though i took a slight hit.
