A well documented and fairly trouble free history is worth a trade-off on a few miles. It rarely does a car any good sitting around unused for two years on an outside dealer lot. I brought an SRT-6 convertible from across country just because it was a one owner car purchased new in 2005, with reasonable mileage use since. There were a few closer and with less mileage. But I haven't had a mechanical issue with mine to date.
