I yelled at my girlfriend, how to apologize?

Hello. Yesterday morning during my sleep, my girlfriend took my car without permission to visit her parents (40km from home, and she forgot to take her cellphone, impossible to call her).

I hate when someone touch my car, it's a sport model and I take care of it.

When she returned in the afternoon I was very upset and angry, she had damaged one of the mag cause she can't park correctly, so I yelled at her but maybe too much because she was crying after.

She was sad and walked away to collect her car in the garage and returned to her parents. Since she left I have no news of her, its been more than a day, she made a mistake but in fact I love her and I don't care about my car anymore.

I feel like a bastard, how to apologize and get her back?
