I got my 95 for $2500....with 209,000+ miles

That's ok an SR is going in there in about a month. Anyway, before you do any mods, I would do some basic maintainence. Oil change, fuel filter, spark plugs, brakes?, tires?, etc. whatever you think might need some attention. My car spent most of it's life in the inner city getting abused, it isn't worth it to do much maintance on it since I'm getting the sr in a few weeks. But in your case, a good tune up will go a long way.
