I sympathize with you. I have experienced a lot of that in more than 30 years of driving my own cars. It seems that the target of this kind of accidents are the new ones and at the time na ingat na ingat ka. Masasabi mo na lang, "Ni hindi man lang pina-abot mag-one year old ang kotse ko". But over the years, I have learned that it is part of having and driving a car.
If it is a small dimple lang, ipa-paintless dent repair mo na lang. Kung maibabalik yung original, the memory of the accident will fade.
