If I were to go back to a WRX, it would have to be a wagon. That's why we traded it out in 07, cargo/kid space. My only complaint was the material the seats were made of... snagged too easily, at least for me. Other than that the car was great and mine was only running Cobb Stage 1 with an 05 STI catback, K&N and some silicone IC pipes. Not much in the way of mods.
Good luck with the sale. Yours looks mighty fine.
