You'll benefit more there first, Cd is not a constant but varies as a function of speed, if most of your driving is less than 55mph you'll see less from aero and more from mechanical. imo
Maintenance and cleaning is my first priority. I'm going to replace the valve cover gaskets and timing belt first thing. If I see any signs of head gasket issues, I'll just rebuild the whole thing.

It still has the original 12 inch rims. They have pretty good tires now but supposedly everyone upgrades because tires are hard to find.
