I have a Nissan LEAF and have owned it since new (so I know it's never been hit). Looking at the panel fit between the rear bumpers and the quarter panels, that car looks worse than some cars I've seen that have been hit.
>Tesla forums are littered with complaints about fit and finish. Have a look at the .pdf in this thread, which shows bad sealing, poor parts fitment and even rust on the rear seat brackets. [0]
And that is for the Model X, from what I've heard, the Model S was even worse.
