I'm with wayner on the PM approach. Also doesn't hurt that I work in aerospace, where everything is replaced on a schedule based on predicted reliability. With a new car, I replace stuff before I think it will break. With a used car, the first thing I do is to "baseline" the usual maintenance/repair stuff if I don't have recent receipts. So far the RX7 has had the fuel filter sock, spark plugs, wires, ground cleaning, air filter, battery, rebuilt shifter, and tires. This weekend will be fuel filter, oxygen sensor, Jet-Hot coated downpipe to replace the failure prone pre-cat, and an aftermarket ECU to protect against boost creep. After that will be transmission and diff fluid, coolant, brakes, suspension bushings, and dampers. Should be like a new car again!
