If I get a scratch on a car door and I am compensated, do I have to repair or can I just keep the money and live with the dent or scratch?
(This may be a similar question but I am unsure so I made this one a separate question.)
The question's "I am paid for repairs" may be misleading: I seem to recall that you're paid for the difference between the market value of the car before it was damaged and its value damaged: that the payment has nothing to do with repairs. (This differs from assault on a person, where one pays for the difference in value (as above, nezek), repairs (ripuy), lost wages (sheves), and pain and suffering (boshes and tzaar).) Therefore, I can't see why the owner would need to repair his car. But I have no source.
