Nice car. I'd have bought it also (I am under a moratorium on car purchases under a new but strict domestic policy...).
There is a high rear hatch spoiler that can be fitted that came from the factory and it predates Subaru's spoiler on the Impreza by two decades. There are also fog lamps for the nose that looked very aggressive at the time.
I'd leave it as is and enjoy it for what it is.
Finding 225/50/15s is still feasible (I use them on my MR2) but it's getting harder and harder.
