My sister gave it to me when it has 130K miles on it. I was driving it to DC every day 100+ miles alot of weekends too. Right away, I replaced the fluids. Mobil1 ES in the engine, Mobil1 auto trans fluid in the power steering sump, Mobil1 automatic transmission fluid in the transmission. I had to fill and drain the differential fluid 3 times until it turned clear colored again. When the 3.73 gears went in, they used Amsoil gear oil/fluid. I replaced the radiator and thermostat. Totally rebuilt the braking system components. I replace the fuel filter every oil change. I've always used Autolite copper core plugs in the engine. Replaced the wires and ignition coil because of age. Eventually the suspension was rebuilt. Thats pretty much it. I try to eliminate any noise, bang, or clunk as soon as I hear it. Runs great right now. Brand new dual exhaust and it's dyno tuned.
