I've just rented a car from A Rental and upon receiving the car from the agent, I did point out that there were few minor scratches on the car and asked the agent to note it down in the invoice which she did. When I returned the car duly, she pointed out that there was one new scratch which I could not recall inflicting it while driving. She insisted it was a new scratch which I thought otherwise, but she forfeited my refund of $210 anyway. Since I have no proof tat the scratch wasn't from me, i gave in. So my advise to people who want to rent a car from them, do take photos of all the scratches on the car so that they could not make false claims against you.
