Having recently passed 40K (and having survived 6 weeks of diagnosing a phantom electrical problem that turned out to be wires separating at the very base of the ignition switch), I have settled back into roughly 500 miles per week. What sort of longevity, mileage wise, should I expect from this model? I'd like to run it up to 100K, but won't hesitate to switch to a newer and/or lower mileage model if I start leaving a trail of parts.
