As the owner of the car, I’d send the valet company the bill for the damages they did to my vehicle. If they did not pay me for the damages, I’d take that valet company to court for those damages. This is why valet companies are required to car insurance to be able to do business. A valet walked up to park his car, which my friend of course declined, but the owner insisted on valet. If a valet crashes your car, then the company that hired that valet is responsible for the damages.
