Will this bolt directly to my C300 without any drilling?

Yes. This bracket mounts at the factory anchor points on the front fascia — no drilling or modification needed. Test-fit before final tightening to confirm alignment with your plate.

Does this come with hardware to attach the license plate itself?

The bracket itself is included. Confirm your state's plate-mounting hardware (bolts, washers) before installation — most DIYers use standard stainless fasteners from local hardware stock.

Can I remove this bracket later without damaging the bumper?

Clean removal is possible since it uses factory mounting points. Once unbolted, the anchor areas remain intact. Fill any visible holes with touch-up paint if you plan to remove it permanently.
