Doug's Take I love this version of the WRX STI, as it's smaller than the current model, its flat-4 engine sounds awesome, and it's a LOT of fun to drive. This particular example benefits from a documented engine replacement performed in 2016 – a MAJOR item that should give the next owner valuable peace of mind. It also features numerous modifications intended to improve performance and styling, and it spent most of its life registered in warm-weather Texas and New Mexico.
