Close to pulling the trigger... any specifics to watch for??

I'm late to the party on this, but check the underside of the air intake plenum for rust through. Leaves fall into the area and hold moisture and eventually rot through, common problem, not easy or cheap to fix. Just my 2 cents worth, but I'm dealing with the issue right now, and mine isn't nearly as bad as some I've seen. All the best with your new acquisition!
