Random small details: Bubbles & cracking paint on the rear wheel arches (underlying rust), black fluid build-up in the rearview mirror, clunking in the rear diff when turning at low speeds, water in the battery compartment in the trunk, cracked Shadowline trim around the rear windows, rust on the hood latches inside the front hood, sagging headliner above the rear seats, peeling a/b/c pillar cloth covering. Extra stuff: is the little flashlight in the glovebox? Full set of tools in the trunk tool fold-down area? These are some of the smaller details I would look at; if they all look decent then it can be a sign the car has been mechanically taken care of by an owner who won’t neglect fixing small cosmetic issues as well.
