Apology Letter For Damaged to a Borrowed Car
Dear {Recipient},
I'm terribly sorry for what happened to your car. I can't believe I let this happen on my watch! You entrusted me with your beloved vehicle and I let you down. I feel so ashamed every time I think of the {scratch on the bumper/dent on the door/something else}.
I am willing to pay for the repairs or insurance deductible. Please let me know the amount and I'll send a check right away.
Thanks again for letting me borrow your car and apologies again for the trouble.
Sincerely,
{Your Name}
