Since we've owned this car since '03, I'm thinking this might be the year to replace the coolant. Is factory coolant required, or will any good quality coolant do the job?
I ask this since another list I subscribe to (for another make) has consensus that high-end M-B coolant is the best replacement (for that make, which is not M-B).

Subaru coolant isn't absolutely necessary, but there are enough considerations on chemical makeup that you may as well go with OEM Subaru coolant.
Be aware that changing coolant on a Soob usually requires "burping" after the fill.
Coolant is supposed to be replaced more often than every 4 years. So don't neglect to do it soon.
If you don't have a dealer do it, you will need the "coolant conditioner" that is supposed to help mitigate outside gasket problems. (Especially on that year of Subaru).
You can get it here:
Aside from that, (as the other poster mentioned) there are quirks to Subarus that need to be addressed during the coolant change process.
