Chances are those wheels have been around since at least 2012 so they've probably got a good bit of miles on them. A good refinish shouldn't cost more than about $150 per wheel. See if you can get the dealer to either discount that cost or take care of the refinish for you (make sure you get final approval of the results). You can probably get them to replace the tires too if they can refinish the wheels.
