Accidental or Intentional?

Just two weeks ago, I was surprised when my colleague told me that he noticed something wrong in my toy car.  He asked whether I figured in an accident that resulted to its damage.  I did not remember I bumped into something or vice versa.  Considering the extent of the damage, it would be impossible that one cannot notice it nor feel its impact.

You may be the judge, is it accidental or intentional?
