For what it's worth: a fig tree was delivered to me from Spain a few years ago in the mid of summer. It has stayed inside a lorry for almost a week, no light, no water, just scorcing heat inside.
Since it was a bargain I did not complain about it when it was delivered. I watered it, put it outside and after just a fortnight, the leaves turned from almost yellow to bright green. Very robust plants, those figs.
