a few dealers I've used have always taken pictures of your car upon checkin from multiple angles with a DSLR camera, meaning it's high-quality/resolution which can be zoomed in to see defects. This is used to protect them in case of scratches, but obviously this protects you too... hopefully they did that with your car... find out.

My dealer had scratched up the front fender / aero-kit pretty bad and they fixed it for me good as new. But I alerted them to it when the valet got the car for me. ALWAYS inspect. They've also dinged up my rims at least twice, but I've let that go as that particular wheel was scratched somewhat already. Just a way of life for wheels.
