I did some stuff with it that's entirely a non-issue with a wagon, but impossible with a sedan.
Discovered the "surface rust" on the rear of the shock tower is coming from the wheel well.
(so the scope of the parts being plated over just increased)
Got tired of having to pry the cupholder out of the dash with a pocketknife, so I re-engineered it so it springs out again.
(plastic pin that it pivots around snapped off, replaced with an m5x0.8 machine screw)
Then, even though it was a factor rather than "the cause" I threw away all the wet foam that goes under the interior panels. And, since I wasn't going to be making/fixing this car to be stock or ST legal I made myself feel better by scraping all the sound deadening off the floor of the hatch. Then when I realized some of the holes covered by the sound deadening went right outside of the car, I covered those with gaffer tape.
