With regards to your personalised perspex plates, check with DOT. I can't say for sure, but I would think that since you paid the premium for the plates originally, that a remake would be much cheaper than the original make and issue to you.

Worth a phone call to them, but in any event, the offending driver is culpable for the costs.
