I have recently moved from a state requiring both front and rear license plates to one requiring only the rear plate; Wisconsin to Florida. Is there a method to repair the front fascia after the front license plate bracket is removed?
I have a 2011 XKR 175 and the front end will certainly look better without the license plate.

 

You can have it repaired professionally, but it would likely cost at least $500.

For an inexpensive solution, I would suggest getting plastic snap-in plugs to fit the hole and thickness of the bumper cover such as McMaster-Carr. Then spray paint it to match with custom can from Touch Up Paint and Accessories | AutomotiveTouchup
